Codedeploy Notifications as a Service

Emerson Loureiro aws

After moving our software stack to AWS, some of us here at Gilt have started deploying our services to production using AWS’s Codedeploy. Before that, in a not-so-distant past, we used an in-house tool for deployments - IonCannon. One of the things IonCannon provided were deployment notifications. In particular, it would:

  1. Send an email to the developer who pushed the deployment, for successful and failed deployments;
  2. Send a new deployment notification to Newrelic;
  3. Optionally, send a Hipchat message to a pre-configured room, also for successful and failed deployments.

These notifications had a few advantages.

  1. If you - like me - prefer to switch to something else while the deployment is ongoing, you would probably want to be notified when it is finished; i.e., “don’t call me, I’ll call you”-sort of thing. The email notifications were a good fit for that;
  2. Having notifications sent via more open channels, like Newrelic and Hipchat, meant that anyone in the team - or in the company really - could quickly check when a given service was released, which version was released, whether it was out on a canary or all production nodes, etc. In Newrelic, in particular, one can see for example, all deployments for a given time range and filter out errors based on specific deployments. These can come in handy when trying to identify a potentially broken release.

Codedeploy, however, doesn’t provide anything out-of-the-box for deployment notifications. With that in mind, we have started looking at the different options available to achieve that. For example, AWS itself has the necessary components to get that working - e.g., SNS topics, Codedeploy hooks - but that means you have to do the gluing between your application and those components yourself and, with Codedeploy hooks in particular, on an application-by-application basis. Initially, what some of us have done was a really simple Newrelic deployment notification, by hitting Newrelic’s deployment API in the Codedeploy healthcheck script. This approach worked well for successful deployments. Because the healthcheck script is the last hook called by Codedeploy, it was safe to assume the deployment was successful. It was also good for realtime purposes, i.e., the deployment notification would be triggered at the same as the deployment itself.

Despite that, one can easily think of more complicated workflows. For example, let’s say I want to notify on failed deployments now. Since a failure can happen at any stage of the deployment, the healthcheck hook will not even be called in those cases. Apart from failed deployments, it’s reasonable to think about notifications via email, SNS topics, and so on. All of that essentially means adding various logic to different Codedeploy hooks, triggering the notifications “manually” from there - which for things like sending an email isn’t as simple as hitting an endpoint. Duplication of that logic across different services is then inevitable. An alternative to that would be Cloudtrail and a Lambda. However, given the delay for delivering Cloudtrail log files to S3, we would lose too much on the realtime aspect of the notifications. One good aspect of this approach, though, is that it could handle different applications with a single Lambda.

So, the ideal approach here would be one that could deliver realtime notifications - or as close to that as possible - and handle multiple Codedeploy applications. Given that, the solution we have been using to some extent here at Gilt is to provide deployment notifications in a configurable way, as a service, by talking directly to Codedeploy. Below is a high-level view of our solution. In essence, our codedeploy notifications service gets deployments directly from Codedeploy and relies on a number of different channels - e.g., SNS, SES, Newrelic, Hipchat - for sending out deployment notifications. These channels are implemented and plugged in as we need though, so not really part of the core of our service. Dynamo DB is used for persisting registrations - more on that below - and successful notifications - to prevent duplications.

fancy highlevel view

We have decided to require explicit registration for any application that we would want to have deployment notifications. There are two reasons for doing this. First, our service runs in an account where different applications - from different teams - are running, so we wanted the ability to select which of those would have deployment notifications triggered. Second, as part of registering the application, we wanted the ability to define over which channels those notifications would be triggered. So our service provides an endpoint that takes care of registering a Codedeploy application. Here’s what a request to this endpoint look like.

curl -H 'Content-type: application/json' -X POST -d '{ "codedeploy_application_name": "CODE_DEPLOY_APPLICATION_NAME", "notifications": [ { "newrelic_notification": { "application_name": "NEWRELIC_APPLICATION_NAME" } } ] }' 'http://localhost:9000/registrations'

This will register a Codedeploy application and set it up for Newrelic notifications. The Codedeploy application name -CODE_DEPLOY_APPLICATION_NAME above - is used for fetching deployments, so it needs to be the exact name of the application in Codedeploy. The Newrelic application name - NEWRELIC_APPLICATION_NAME - on the other hand, is used to tell Newrelic which application the deployment notification belongs to. Even though we have only illustrated a single channel above, multiple ones can be provided, each always containing setup specific to that channel - e.g., SMTP server for Emails, topic name for SNS.

For each registered application, the service then queries Codedeploy for all deployments across all of their deployment groups, for a given time window. Any deployment marked as successful will have a notification triggered over all channels configured for that application. Each successful notification is then saved in Dynamo. That’s done on scheduled-basis - i.e., every time a pre-configured amount of time passes the service checks again for deployments. This means we can make the deployment notifications as realtime as possible, by just adjusting the scheduling frequency.

Our idea of a notification channel is completely generic. In other words, it’s independent with regards to the reason behind the notification. In that sense, it would be perfectly possible to register Newrelic notifications for failed deployments - even though in practical terms it would be a bit of nonsense, given Newrelic notifications are meant for successful deployments only. We leave it up to those registering their applications to make sure the setup is sound.

Even though we have talked about a single service doing all of the above, our solution, in fact, is split into two projects. One is a library - codedeploy-notifications - which provides an API for adding registrations, listing Codedeploy deployments, and triggering notifications. The service is then separate, simply integrating with the library. For example, for the registration endpoint we described above, the service uses the following API from codedeploy-notifications under the hood.

val amazonDynamoClient = ...
val registrationDao = new DynamoDbRegistrationDao(amazonDynamoClient)
val newRelicNotificationSetup = NewrelicNotificationSetup("NewrelicApplicationName")
val newRegistration = NewRegistration("CodedeployApplicationName", Seq(newRelicNotificationSetup))
registrationDao.newRegistration(newRegistration)

Splitting things this way means that the library - being free from anything Gilt-specific - can be open-sourced much more easily. Also, it gives users the freedom to choose how to integrate with it. Whereas we currently have it integrated with a small dedicated service, on a T2 Nano instance, others may find it better to integrate it with a service responsible for doing multiple things. Even though the service itself isn’t something open-sourcable - as it would contain API keys, passwords, and such - and it’s currently being owned by one team only, it is still generic enough so it can be used by other teams.

We have been using this approach for some of our Codedeploy applications, and have been quite happy with the results. The notifications are being triggered with minimal delay - within a couple of seconds for the vast majority of the deployments and under 10 seconds in the worst-case scenarios. The codedeploy-notifications library is open source from day 1 and available here. It currently supports Newrelic notifications, for successful deployments, and there is current work to support Emails as well as notifications for failed deployments. Suggestions, comments, and contributions are, of course, always welcome.

Using tvOS, the Focus Engine & Swift to build Apple TV apps

Evan Maloney tvOS

At the Apple product launch event in September, Gilt demonstrated its upcoming “Gilt on TV” app for the Apple TV. (If you missed the demo and would like to see it, Apple has the video available on their website. Eddy Cue’s introduction of Gilt begins at the 74:20 mark.)

Last night, at the iOSoho meetup, I presented some of the things our team learned while developing that application, such as:

  • Similarities and differences with iOS development
  • The tvOS interaction model: What is “focus” and how does it work?
  • Interacting with the Focus Engine to set up your initial UI state
  • How the Focus Engine sees your views onscreen, and how that affects navigation
  • Using focus guides to make your UI easier to navigate
  • Swift: Is it ready for full-scale app development?

ION-Roller - Immutable software deployment service for AWS

Natalia Bartol aws deployment

Gilt has been at the forefront of the wave of microservice architecture. With the advantage of many individual services that do one thing well comes increased complexity of service management.

Our previous system was based on a reasonably traditional model of deployment scripts that simply replaced software on machines in order, and performed health checks before proceeding to the next server. A number of issues caused friction in attempts to release software. One was that in spite of services being run as microservices, many deployment decisions had to be done in lockstep, due to the shared platform. Another was that services that took a long time to start up (cache loads, etc.) had a large cost when the service was stopped; if a new release had to be rolled back, this could take more time than people might like.

Two ideas for software deployment arose from this. One was to separate the environments for each piece of software, and due to this, Gilt became an early leader in trials of the Docker deployment platform. Another idea was inspired by the principles of functional programming, where data was not changed in-place, but was modified by creating a new copy with the changes applied. This idea, “immutable infrastructure”, could allow new software releases, without the risk attached to shutting down the previous software version, as rollbacks would be quick and painless.

A third constraint appeared, which was not core to the concept, but based on the realities of Gilt’s deployment environments, which was that the AWS services, and EC2 computing platform, were going to be central to any service we created.

ION-Roller took these ideas, to create a deployment tool for immutable releases of software, using Docker environments, on top of the AWS infrastructure.

Following our article about deploying microservices published in InfoQ, now we made our work publicly available: https://github.com/gilt/ionroller. Check out a short demo!

Since development of the product started, Amazon has released a number of features in their own products (including the release of, and then enhancements to, the CodeDeploy service for deploying applications with EC2). In many cases, this is sufficient, especially for small companies which do not want to run their own deployment services. The major difference between the approaches is that CodeDeploy is not currently “immutable”, that is, it replaces the software as it installs new versions. We expect future changes to AWS services to further close the gap in functionality.

Private NPM Modules: A Song of Fire and Ice

Andrew Powell npm

Grab a coffee or pop and a snack, this is a read.

Several years ago, Gilt Tech decided to adopt a new strategy for developing the overall Gilt platform. It was determined that many small applications should comprise Gilt.com, rather than one (or few) large monolithic applications. We called this strategy ‘Lots of Small Applications,’ or ‘LOSA.’ Key to LOSA were decentralized, distributed front-end assets. Enter NPM.

Our requirements for how this was to work was varied, and we authored build tools to facilitate them. Our build tools solved many problems that at the time, didn’t have solutions. We also knew we couldn’t rely on external services to host our modules, because we need to know that the registry these little guys were stored in needed to always be available. NPM was still new, and npmjs.org was still a baby back then. Third-party SaaS providers weren’t a thing for this yet. And so we spun up our own NPM registry in-house. This worked for years, and worked well - until one day it became obvious that we were hopelessly out of date.

June 2014: A framework for developing NodeJS applications at Gilt took shape, and the need to start installing public modules from npmjs.org became real. The architects of the in-house registry had long-since parted ways with Gilt, and we scrambled to try and update an aged system. We attempted to implement a proxy from our private registry to the public. Things worked, but not well, and it was decided that we’d look to a third-party for our registry needs. We eventually settled on a well-known company in the NodeJS space. We were able to migrate our internal registry to their service, and everything worked very, very well.

In February of this year we were informed that a very large entity, we’ll call them “MovableUncle,” had purchased the registry-hosting company and they would cease their registry business. We knew we’d have to move off of the platform and began carefully and cautiously considering alternatives. We were told that we’d have until December 2015 - and then someone rolled in the dumpster and lit that baby afire. The registry company experienced massive attrition, including all of their support staff, resulting in a near-complete inability to get support. Our data was locked there, and despite exhausting many channels of communication, we were unable to procure a backup archive of our data. Some amount of panic set in when their website was updated to show August 2015 as the cutoff date.

Without knowing for sure just when the service would go down, we knew it was time to act, and quickly. We identified the three most viable options for moving forward: Hosting in-house again, going with another private registry SaaS provider that Gilt was already using for a different service, or going with the newly announced Private Modules offering on npmjs.org.

After much discussion and weighing the options against one-another, we decided to bite the bullet and go with npmjs.org. That bullet we had to bite meant a lot of changes internally. Their scoping mechanism while elegant for installing modules and organization, was an enormous pain point for Gilt - it meant we had to update the names and dependencies for 220 modules. We’d also be losing our history of published modules covering nearly four years. Representatives for npmjs.org explicitly told us there was no way to import a registry, even if we could get a backup out of the dumpster fire. That also meant that we’d have to republish 220 modules.

‘Aint Got Time To Bleed, as August was fast-approaching. This process required either a metric poop-ton of man-hours, or some quasi-clever scripts. We put together two NodeJS scripts;

  1. npm-registry-backup would pull down a manual backup of our registry. That would mean iterating over all of our modules in the repo, fetching the npm info for each, and downloading the tarball for each revision.
  2. npm-scope would iterate through a target directory looking for package.json files, update the name by adding our npmjs.org scope, adding the scope to any private modules in the dependencies property, and then finally publishing the module to npmjs.org. This script also allowed us to automagically update our apps that had private module dependencies.

We’ll make those scripts publicly available in the coming week(s) once we’re out of the forest. From start to finish the process took about 9 man-hours (3 hours / 3 fellas) for backup and update of 220 modules, distributed through 14 different git repositories. Getting everything just right across the org was another matter altogether. Switching module paradigms isn’t a trivial thing when the org has relied on one model for a few years.

Knowing Is Half The Battle and to say we learned a lot from this ordeal would be an understatement the size of Texas.

Build Tools

One of my favorite Gilt-isms is “It solved the problem at the time.” Our primary build tool (named ui-build) for front-end assets was written a few years ago when we still thought Rake was all the hotness. It’s a brilliant piece of code and study in Ruby polymorphism - unfortunately it’s infested with massively complex regular expressions, hardcoded assumptions about filesystem locations, and chock-full of black magic. “Black magic” is the term we use at Gilt for all of the things in ui-build that were written by people no longer with the company, for which we don’t know it’s doing. Once we updated ui-build to handle scoped modules, we learned that we had to republish around 80 modules, due to black magic. We require publishing of modules to go through the build tool so that things like linting and verification of certain data and standards are performed prior to actually publishing to npm. We learned that in that process, things like automatic compilation of LESS and manipulation of vendor code, are done SILENTLY.

While our next-generation, gulp-based build tool is being polished and rolled-out, we’ve used this lesson to ensure that we don’t have gaps in knowledge and documentation like we experienced with ui-build. We’re also using this opportunity to explore how we can use the standard processes of npm to perform pre-publish or post-install steps and remove the need for black magic.

Maintenance, Maintenance, Maintenance

Some of our apps are so out-of-date they might as well be wearing bell-bottoms and driving Gremlins. So so so many apps had dependencies on module versions that were a year+ old. Remember - we lost that revision history in the registry when we moved to npmjs.org. Things blew up in epic fashion when attempting builds of many of our less-frequently-maintained apps. Some of the dependencies were so stubborn that we had to republish the tarballs for old versions that we had pulled down from npm-registry-backup.

We need to be better at updating our apps. It doesn’t always make cost-benefit sense to management, but it helps eliminate technical debt that we paid for in man-hours during this process. On top of the the original 9 man-hours, we had to spend roughly an additional 32 man-hours (8 hours / 4 fellas) with subsequent clean-up. There is progress on this front, however; Gilt Tech recently embarked on an ownership campaign internally called the ‘Genome Project’ which should help address this concern.

Conclusion, or Potty Break

Overall the move was a success. We’re still chasing the occasional edge case and build problem, but the major hurdles have been overcome. The improvement in speed and reliability of NPM over the SaaS registry host has been marked. We’re able to use the latest features of the NPM registry and have regained the ability to unpublish; something we lost with the SaaS host. The technical improvements coupled with the knowledge we’ve gained have made the endeavor worthwhile. And unless “MovableUncle” inexplicably acquires npmsj.org, we’ve set the company up for stability in this area for some time to come.

Gilt Tech Blog Moves to Github

In continuing the march towards a more open Gilt Tech, we’ve made the switch to Github Pages and Jekyll from Tumblr.

You can view the entirety of this blog’s code and content here: https://github.com/gilt/tech-blog.

Why We Did This

First and foremost: control. We’ve got control over the layout and design of the blog from top to bottom, without restriction and without any kind of a funky theming engine to wrestle with. We’re really good at this kind of thing (we should be, after all) and we’ve ended up with a blog design that matches elements of gilt.com.

We’ve also got better control over how we write posts. We’re a fairly large, distributed organization, and coordinating the setup, permissions, et al for Tumblr was kind of a pain. There was also very little positive feedback about the authoring experience. With the move everyone is able to author in their editor of choice and go through the already familiar process of submitting the post to the tech-blog repository.

We Used Technology

Jekyll Bootstrap is a fantastic bootstrap/scaffolding package put together to quickly spin up a blog. While we customized the bajeezus out of it, which was incredibly quick and painless, and rolled our own ‘gilt’ theme, we used a healthy chunk of what it ships with by default. We did roll our own helpful tidbits, like the authors page, for which you can view the source here.

Github Pages. If you haven’t looked into Github Pages for simple hosted websites or project websites yet, give it a gander. It’s a phenomenal way to quickly spin up a site, and it’s Jekyll support is pretty great.

Fin

We hope you like the new digs, and we’re forecasting a lot more great content to come.

Introducing Gumshoe

Andrew Powell analytics

An analytics and event tracking sleuth.

In late 2014 Gilt received word that a core feature of Google Analytics (henceforth known as GA) would be removed in the next iteration of the platform. The ability to redirect collected data and events to a secondary endpoint had grown critical to our the analization of user behavior, patterns, and effectiveness of our user experience, as well as sales forecasting and predictive modeling. Our two most viable options for retaining this ability were to implement another tracking platform from a different vendor or create and implement our own, tailored to our specific needs.

https://github.com/gilt/Gumshoe

After taking a hard look at the heavy hitters of the analytics platform sphere it was decided that we’d take the divergent route and roll our own analytics and event tracking library. We won’t go into detail on why we passed on big players like Snowplow, Omniture, CoreMetrics, et al. Rather, we’ll focus on Gumshoe and its merits.

What Did We Need?

To anyone in development, marketing, or data sciences on the web, our list of needs will sound quite familiar.

First and foremost we required parity with GA’s base page data. The industry has come to be reliant and has standardized on the kind of data that GA collects for various reporting, including vital year-over-year reporting. So no shockers there.

As performance-minded developers we also had a low page footprint in mind.

We desperately needed organized event names and data. One major shortcoming of GA was the lack of enforcement of any kind of standard in event naming and data. Arbitrary event names and varying event data formats produced migraines the size of Mount Fuji for our Data Scientists. It wasn’t uncommon to have the same target event with several different names, in different applications, with different data in different delimited formats.

Related to the variance in event data, we were looking for a high degree of data integrity and confidence.

And last but not least, a low delivery failure or miss rate for the data collection.

Rolling Our Own

Events are events are events. In Gumshoe, everything is an event. There’s no disambiguation between page views, virtual page views, or custom user events. Everything is an event, and it’s a core tenant of Gumshoe.

Right off the bat, parity with GA was key. We started by breaking down the data that GA collected from each page view, and moved forward from there. A basic Gumshoe event consists of the following:

pageData
eventName
eventData

pageData consists of the GA parity data.
eventName is self-explanatory; the name of the event we’re passing.
eventData is custom data passed by the consumer which should be associated with an event.

Wunderbar! We had the recipe for sending a page view event. But how do we set this up so that others can easily send these events to where ever they’d like? Enter the transport.

Transports are the mechanism(s) by which consumers instruct Gumshoe on how it should send the data for each event. One can configure Gumshoe to send to multiple transports, or a single transport, it’s your choice. A brief example from the repository:

(function (root) {

  var gumshoe = root.gumshoe;

  gumshoe.transport({

    name: 'example-transport',

    send: function (data) {
      console.log('Gumshoe: Test Transport: Sending...');
      console.log(data);
    },

    map: function (data) {
      return {
        customData: {
          someData: true
        },
        ipAddress: '192.168.1.1'
      };
    }

  });

})(this);

The send method is responsible for actually sending the data. Gumshoe bundles the https://github.com/gilt/reqwest library, which any transports can freely use. At Gilt we use reqwest.js to send the data to our backend event stack, which we’ll cover in subsequent blog posts.

The map method allows consumers to extend the data which Gumshoe is sending through the transport. At Gilt we use this method to attach a giltData object that is sent along side pageData and contains vital Gilt-specific data for every single event that we send.

Using Gumshoe

Once you’ve got Gumshoe included on your page and you’ve specified a transport, you’ll need to initialize the library. It’s as simple as specifying the transport:

// tell gumshoe to use our transport  
window.gumshoe({ transport: 'example-transport' });  

And sending an event:

window.gumshoe.send('page.view', {});  

What’s Next

In forthcoming posts we’ll be talking more about the other goals we listed, specifically how we internally solved event organization, event naming standardization, data integrity, and the remainder of the stack that takes over once Gumshoe has delivered the payload.

We’ve been using Gumshoe on gilt.com for some time now, and have been running constant parity comparisons against GA and we’re very happy with the results thus far. However, we’d be bonkers to claim that Gumshoe is perfect. We’ve tailored Gumshoe to be extensible but so far it’s only been targeted for use at Gilt. We’d love feedback from the community at large. And if you feel you might be able to use Gumshoe, but find it lacking, we’d love to talk about how it can be improved.
