DevOps Training, Hands-On Labs & Cloud Coaching

Another deployment strategy people often see are bluegreen deployments. Deployment teams need to disambiguate which services will be consistently deployed, and which services will be shared across versions of the application. So now within our pull request view, we’ll be able to see a big checkmark here, which shows that all of the relevant ci checks have passed. And then you can even automate within GitHub or other source code management platforms that certain checks must pass entirely. So you can automate that all ci checks must pass before a change could be merged. Let’s make sure that developers are never reviewing code that’s so obviously broken that it’s breaking your tests.

So beyond just the methodology, which is something that maybe the technical leaders and CEO would care about, there’s a subfield of DevOps engineering, and this is usually what engineers mean. You will learn what DevOps is, continuous integration, continuous deployment strategies, and application performance management. Many DevOps practices are commonly used in programming and web development, it is important to understand key terms and technologies.

So that only if all of the checks pass, can the commit be merged and shown to users. Let’s take a look at the ephemeral environment just to double check that the color is the one we want. So bluegreen deployments are powerful and extensible deployment strategy that works well with teams that are deploying a few times per day. It can use deployment scenarios, where there’s many services being deployed many times per day. So rolling deployments are one of the most popular deployment strategies. And we’ll talk about the pros and cons of different deployment strategies throughout this section.

If you’re working on a distributed web scraper, and you’re scraping tasks take days, for example, you might need your clusters to last until the last job is finished, to ensure things continue working as expected. So if you have version one of the application, you switch over to version two, you realize version two is having problems, you might want to push version three very quickly, which addresses those problems. But version one would be the only place you could deploy version three. And to avoid having to micromanage starting and stopping environments, it’s easiest to use a hosted provider.

However, as I mentioned, it’s possible to run DNS internally. It would be ideal if in our nginx configuration, we could specify HTTP full colon slash slash front end and then have front end resolve to the IP of our front end service. That way we wouldn’t have to change anything except for the DNS configuration. And then the reverse proxy would take the user’s request and send it to the appropriate, they view on that front end or back end, depending on what the user asked to connect to. And then from there, everything else would be the same.

Let’s create a new pull request with these changes and see how that looks. So now that we have our SSH key within the CI server, and these steps are running after tests are passed, all we have to do is copy our command and run it as if it was part of a CI process. In a regular deployment of clusters that only be shut off after all of their long running jobs are done processing. This can be mitigated by increasing the number of services being turned on and shut off at a time, which is sometimes called a burst limit, or a rolling deployment size.
