What’s Blue Inexperienced Deployment and what are it benefits and downsides?



Deployment is the method of updating code and different actions on the server to make software program accessible to be used.

Within the present state of affairs, there is a rise in demand for steady deployment to remain present with software program updates, in order to present the consumer with good high quality software expertise. There are lots of strategies accessible out there for this, and on this article, we can be discussing about Blue Inexperienced Deployment.

What’s Blue-Inexperienced Deployment?

Blue Inexperienced Deployment is a software program launch mannequin that consists of two similar manufacturing environments; Blue and Inexperienced, configured in a means the place one atmosphere is reside and the opposite is in staging (idle) state.

The concept behind that is to redirect site visitors between two environments operating with a unique model of the appliance.

This course of eliminates downtime and reduces the chance that occurs as a result of deployment.  In case any error happens with the brand new model, we are able to instantly roll again to the steady model by swapping the atmosphere.

In some organizations, it’s also termed as Purple Black Deployment.

Working of Blue Inexperienced Deployment:

To implement Blue-Inexperienced deployment, there needs to be two similar environments. Additionally, this requires Router or Load Balancer in order that site visitors will be routed to the specified atmosphere.

Within the picture, we now have two manufacturing environments, Blue and Inexperienced. The Blue atmosphere is one the place present (as an example model 1) of the appliance is operating and is reside as effectively. All of the site visitors of the appliance is directed to Blue by Router or load balancer (as per the infra arrange). In the meantime, model 2 of the appliance is deployed and examined on Inexperienced Setting.

At the moment, at this stage, we are able to check with Blue atmosphere as Reside and Inexperienced as idle or at staging state.

As soon as the code for model 2 is examined and prepared to be reside for manufacturing, we redirect the site visitors from Blue Setting to Inexperienced Setting, making Inexperienced as Reside and Blue as a staging atmosphere. If any drawback is detected with the Infrastructure or software after model 2 is made reside, we are able to roll again to the earlier model simply by swapping the atmosphere.

Blue Inexperienced deployment matches all necessities of seamless, protected and totally reversible circumstances for best deployment, however there are some practices that want to be adopted for clean course of, for eg. automating the workflow so that there’s minimal human intervention, decreasing possibilities of guide error.

Together with that, it’s also necessary to maintain monitoring in place for Blue Inexperienced software.

Instruments and Companies for Set-Up:

Based mostly upon infrastructure and software, there are numerous providers i.e. Docker, Kubernetes,  Cloud, Cloudfoundry and many others accessible which can be utilized to implement Blue-Inexperienced Deployment.

We can be discussing additional on Blue Inexperienced deployment on Cloud and the steps to implement it.

The arrival of Cloud in Blue-Inexperienced Deployment:

The arrival of cloud computing in deployment has helped the system to cut back related dangers.

Cloud utilities of infra administration, billing and automation have made it simpler to implement Blue-Inexperienced Deployment, making it a faster activity at a decrease price.

AWS Companies for Blue-Inexperienced Deployment:

By using AWS for Blue-Inexperienced Deployment, we are able to entry many providers that assist in automation of deployment and infrastructure i.e. AWS CLI, SDK, ELB, Elastic Beanstalk, CloudFormation and many others. There are a variety of options that AWS offers which we are able to use, a few of them being:

  • DNS Routing with Route53
  • Swapping of Autoscaling Group with ELB
  • Utilizing Elastic Beanstalk and swapping Utility
  • Blue-Inexperienced Deployment utilizing AWS Code Deploy
  • Cloning Stack in OpsWork and Updating DNS.

We are going to talk about Utilizing Elastic Beanstalk and swapping Utility intimately:

Utilizing Elastic Beanstalk and swapping Utility

Elastic Beanstalk offers us with the administration of software and ease in deployment. As soon as we add software code with model 1 on Elastic Beanstalk, it deploys our software in Blue Setting and in case of webserver in our infrastructure, URL is offered.

The above Setting configuration is then copied and launched with the brand new model of application-i.e. Inexperienced Setting. The brand new Inexperienced atmosphere has its personal URL.

As soon as the appliance is up and operating, Elastic Beanstalk offers the URL. At this level of time, our software is up with two environments and URLs, however site visitors goes solely to the Blue Setting.

For Switching the atmosphere to Inexperienced, we have to select Setting URL from the Elastic Beanstalk Console. As soon as DNS adjustments are accomplished, we are able to terminate the Blue Setting.

For Rollback, we have to invoke the Swap Setting URL once more.

Steps to carry out Blue-Inexperienced deployment in AWS:

  • Open Elastic Beanstalk console from AWS and choose the Area the place we have to arrange an atmosphere. 
  • Both we are able to launch a brand new atmosphere or clone the present atmosphere. 
  • Deploy and check the brand new software atmosphere. For deploying, the brand new model chooses Setting and title from the record. Click on on add and deploy. 
  • We are able to use display screen kind to add supply bundle. 
  • On the Overview web page, select Setting motion and select Swap atmosphere URL.
  • Select the atmosphere title, underneath Choose an atmosphere to swap column and click on on Swap.

Who Can Profit from Blue-Inexperienced Deployments?

Blue-Inexperienced Deployment offers us with minimal Down Time and dependable deployment.

Blue-Inexperienced Deployment has grow to be helpful in deploying an software for Improvement Groups, however it will be used underneath the under eventualities:

  • There needs to be similar and remoted environments.
  • There needs to be the availability for router or Load Balancer.
  • System ought to work with Steady Replace.

Totally different Kinds of Deployment

There are a variety of deployment strategies getting used within the trade to deploy the appliance. As a DevOps Engineer, it turns into necessary to know the insights about completely different strategies primarily based on our infrastructure offering and select the proper approach as per the influence on the end-user. 

  1. Blue-Inexperienced Deployment: Blue Inexperienced deployment offers us with excessive availability and rollback in case of crucial bugs discovered. It consists of two environments operating in parallel. One atmosphere can be reside and others can be in staging, thereby, making our software downtime free. 
  2. A/B Deployment: A/B Deployment is just like Blue-Inexperienced Deployment with the distinction that we ship a small quantity of site visitors to a different Server (one other atmosphere). The utilization of A/B Deployment is usually when we have to verify the utilization of options within the software.
    Together with that, it will also be used to verify consumer suggestions on the brand new model. 
  3. Canary Deployment: Canary deployment is used when we have to launch the complete options of the appliance in subsets. Typically in Canary, we now have a set of servers assigned to a unique set of customers. This deployment is necessary when we have to deploy options together with getting suggestions 
  4. Rolling Deployment: In Rolling Deployment, there’s a course of the place we exchange at the moment operating code server with a brand new model in a tandem means. Pausing the deployment is way simpler on this.

Benefits of Blue-Inexperienced Deployment

  1. No Downtime Deployment:  With Blue Inexperienced Deployment, every time there’s a crucial bug discovered on the manufacturing server, site visitors is redirected to different environments. This results in no downtime for the end-user. 
  2. Standby: Each time there’s a system failure, we are able to instantly carry out rollback and recuperate safely with out disturbing the end-user.  With Blue Inexperienced deployment, as soon as we change to the brand new model of software, the older model of the appliance continues to be accessible. Due to this fact, in case of restoration, we are able to simply swap the atmosphere and redirect the site visitors again to the outdated model. Blue Inexperienced has confirmed to be impactful in decreasing threat within the software growth course of. 
  3. Fast Rollback: In some circumstances the place the brand new characteristic isn’t working correctly, we are able to change to the older characteristic of software by performing a rollback. 
  4. Testing in Prod Setting: There are eventualities when deploying a brand new set of code works nice on native, however when deployed within the bigger infrastructure, it turns into problematic. Through the use of Blue-Inexperienced Deployment, we are able to verify the efficiency of code on the Prod server with out disturbing customers.

Disadvantages of Blue-Inexperienced Deployment:

Since many individuals are heading towards Blue-Inexperienced Deployment, there are some circumstances the place this course of isn’t really useful.

In some circumstances, it includes threat which makes deployment extra susceptible to failure and breakdown.

  1. Database Sync Up:- Schema adjustments are advanced to decouple. Within the case of Blue Inexperienced deployment, syncing of database and knowledge adjustments needs to be synchronized between the Blue and Inexperienced atmosphere. In case of relational database, it might result in discrepancies.
  2. QA/UAT Determine of Failure: In some eventualities, with massive infra, it’s potential that generally QA check circumstances is not going to detect errors/bugs in a non-live atmosphere
  3. Dashboard Required: Since we now have two similar manufacturing environments with a unique model of code, whereas operating the deployment it turns into necessary to monitor insights with packages and code at any level of time to set off issues.
  4. Value: For Blue-Inexperienced Deployment, we now have two units of environments operating in parallel all time, thus growing the price of two manufacturing environments and sustaining them.


There isn’t any mounted strategy to deployments that may go well with and work in each situation.

Groups might want to collaborate and work on choosing the proper approach for his or her software, deciding one of the best answer that may work for the good thing about the group and the appliance.
