For each software program growth agency, there comes a time when their software program will must be modified or upgraded. It may well come within the type of a complete model change or fixing a bug discovered within the authentic model.

Now that the brand new model is prepared, right here comes the true process the agency’s DevOps groups should undertake: How will we deploy this new improve seamlessly with out complicating points, making an allowance for that the person expertise of the end-users is a high precedence?

To unravel this humongous process, the DevOps workforce integrates deployment methods into their working procedures. Through the years, totally different methods have been developed to assist software program corporations efficiently deploy new utility and code variations. These methods are known as deployment methods.

On this article, we’ll take a look at what deployment methods are and the assorted varieties of deployment methods, and their technique of utilization. We’ll additionally cowl every approach’s benefits and downsides and when to make use of which deployment technique in your work as a DevOps engineer.

What Is a Deployment Technique?

A deployment technique is any approach employed by DevOps groups to efficiently launch a brand new model of the software program answer they supply. These methods cowl how community visitors in a manufacturing atmosphere is transitioned from the previous model to the brand new model. Based mostly on the agency’s specialty, a deployment technique can affect downtime and the corporate’s operational value.

Varied Forms of Deployment Methods

Now that we perceive what deployment methods are, let’s discover the assorted varieties of deployment methods.

Blue/Inexperienced Deployment

In one of these deployment technique, the brand new model of the software program runs alongside the previous model. Word that you may additionally consult with this as crimson/black deployment technique in some instances.

Right here, the steady or the older model of the appliance is all the time blue or crimson, whereas the newer model is inexperienced or black.

After the brand new model has been examined and licensed to fulfill all the necessities, the load balancer robotically switches the visitors from the older model to the newer model.

The most important benefit of this technique is that it avails a fast replace or rollout of a brand new utility model. Nonetheless, its fundamental drawback is that it’s expensive since you should run each the brand new and previous variations concurrently. Engineers largely use this technique in cellular app growth and deployment.

Canary Deployment

In canary deployment, the deployment workforce units up the brand new model after which step by step shifts the manufacturing visitors from the older model to the newer model. For instance, at a time limit in the course of the deployment course of, the older model may retain 90% of all visitors for the software program whereas the newer model hosts 10% of the visitors. This deployment approach helps the DevOps engineers check the soundness of the brand new model. It makes use of reside visitors from a subset of the end-users at totally different ranges that varies as manufacturing happens.

Canary deployment permits higher efficiency monitoring. It additionally aids in a sooner and higher rollback of the software program if the brand new model fails. Nonetheless, it has a gradual nature and a extra time-consuming deployment cycle.

Recreate Deployment

On this deployment technique, the dev workforce shuts down the previous model of the appliance completely, deploys the brand new model, after which reboots the entire system. This deployment approach creates a system downtime between shutting down the previous software program and booting the brand new one.

It’s cheaper and primarily used when the software program agency needs to alter the appliance from scratch. It doesn’t require a load balancer as there’s no shifting of visitors from one model to a different within the reside manufacturing atmosphere.

However this technique dramatically impacts the tip customers as a result of downtime. Customers should wait till the appliance goes reside once more to make use of the software program. Consequently, not many builders use this technique until they haven’t any different alternative.

Ramped Deployment

The ramped deployment technique step by step modifications the older model to the brand new model. Not like canary deployment, the ramped deployment technique makes its swap by changing cases of the previous utility model with the cases from the brand new utility model one occasion at a time. It’s also possible to name this technique the rolling improve deployment technique.

When builders exchange all cases of the older model, they shut down the older model. The brand new model then controls the entire manufacturing visitors.

This technique offers zero downtime and in addition permits efficiency monitoring. However, the rollback period is lengthy in case there may be an sudden occasion. It’s because the downgrading course of to the preliminary model follows the identical cycle, one occasion at a time.

Shadow Deployment

On this deployment technique, builders deploy the brand new model alongside the previous model. Nonetheless, customers can’t entry the brand new model instantly. Simply because the title suggests, the newest model hides within the shadows. Builders ship a fork or copy of the requests the previous model receives to the shadow model to check how the brand new model will deal with the requests when reside.

This system could be very complicated, and as such, the DevOps engineer needs to be cautious in order that the forked visitors doesn’t create a replica reside request since two variations of the identical system are working.

Shadow deployment lets engineers monitor system efficiency and conduct stability exams. Nevertheless it’s costly and complicated to arrange and may create severe points.

A/B Testing Deployment

In A/B testing deployment, builders deploy the brand new model alongside the older model. Nonetheless, the brand new model is barely accessible to a subset of customers. These customers are chosen based mostly on particular situations and parameters the engineers select. These parameters will be the person’s location, sort of gadget, UI language, and working system.

This technique measures the effectiveness of the appliance’s new performance. After gathering statistics from efficiency monitoring, builders roll out the model that yielded the most effective outcomes to all customers.

Actual-time statistical information will help builders make necessary and favored selections about their software program. Nonetheless, A/B testing could be very complicated to arrange. It additionally requires a extremely smart (and expensive) load balancer.

Higher Deployment with Instruments

Efficiently launching new options with any deployment technique isn’t a straightforward process. DevOps groups want to grasp what values they’ll be delivery to their customers. Fortunately, Plutora affords instruments could make it simpler for DevOps groups to launch or launch new options with any deployment methods.

For instance, launch administration instruments permit corporations to plan and handle their launch, adopting a deployment technique and monitoring analytics. One other instrument that’s nice to have when planning a deployment is the deployment planning instrument. This instrument permits a streamlined deployment course of to reduce threat.

Software program deployment instruments save time as they will handle CI/CD (steady integration/steady supply), automating deployment. These instruments may improve safety as they will combine role-based entry management.


You possibly can deploy a brand new model of your software program utilizing any of those methods. Every of those methods has its deserves and demerits, and every is nice in numerous situations. The one query now’s, what makes essentially the most sense in your DevOps workforce to make use of? Take note your workforce’s, undertaking’s, and firm’s wants and enterprise objectives. Additionally, notice how a lot downtime your organization can afford and different value constraints. Try Plutora and make use of our deployment administration instruments and launch administration platform to help all of your software program deployment actions. Join a personalised demo at present!

For each software program growth agency, there comes a time when their software program will must be modified or upgraded. It may well come within the type of a complete model change or fixing a bug discovered within the authentic model.
