What are different deployment strategies?
A deployment strategy is a way to change or upgrade an application. The aim is to make the change without downtime in a way that the user barely notices the improvements. The most common strategy is to use a blue-green deployment. The route based deployment strategies do not scale the number of pods in the services.
What is an advantage of deploying?
Some of the advantages to software deployment include: Time savings. Software deployment can happen within hours and the process of installation also becomes quicker. The software can be deployed quickly and there is no need of training or learning anything.
What’s a major downside of the Blue-Green deployment strategy?
There are some drawbacks to blue/green deployment. For one thing, running two identical environments is expensive. Database refactoring can fix the schema problem, and a mirror database can fix a few other issues, but in general, caution is necessary when any blue/green deployment involves a database component.
What is Kubernetes deployment strategy?
In Kubernetes, a canary deployment can be done using two Deployments with common pod labels. One replica of the new version is released alongside the old version. Then after some time and if no error is detected, scale up the number of replicas of the new version and delete the old deployment.
Why do we see automated deployment as an indispensable goal?
There are three major types of value delivered by automated deployment. Productivity improves as work that was done through slow manual processes is replaced with automation, and test labs suffer fewer outages. Reducing errors eliminates rework, wait times and the business impact of failures in production.
Why would you want to automate the deployment process?
The 5 Big Benefits
- #1: Deployments become much less error-prone and much more repeatable. Manual deployments are error prone.
- #2: Anyone in the team can deploy software.
- #3: Engineers spend their time developing software.
- #4: Deploying to somewhere new is not a headache.
- #5: You can release more frequently.
What is the purpose of using blue green deployment?
Blue green deployment is an application release model that gradually transfers user traffic from a previous version of an app or microservice to a nearly identical new release—both of which are running in production.
Why do we need blue green deployment?
Blue-green deployment is a technique that reduces downtime and risk by running two identical production environments called Blue and Green. At any time, only one of the environments is live, with the live environment serving all production traffic. This technique can eliminate downtime due to app deployment.
Which is the best strategy for application deployment?
High impact on the user, expect downtime that depends on both shutdown and boot duration of the application. The ramped deployment strategy consists of slowly rolling out a version of an application by replacing instances one after the other until all the instances are rolled out.
What are the pros and cons of the different implementation strategies?
Users have the ability to learn the new system while keeping their legacy environment as well. There is always a fall back available if new system is unacceptable. Users gain early process and software knowledge now that they can use in the subsequent phases. If you are on a tight/limited budget this can prove costly.
What are the pros of a differentiation strategy?
Pros of Differentiation Strategy The pros of creating a differentiation strategy for your business are: Price is no longer the only competitive factor: Differentiation allows factors other than price to come to the forefront. Just because a competitor is cheaper doesn’t mean they will always come out on top.
When to use recreate or ramped deployment strategy?
When releasing to development/staging environments, a recreate or ramped deployment is usually a good choice. When it comes to production, a ramped or blue/green deployment is usually a good fit, but proper testing of the new platform is necessary.
