In this blog post, we will know the advantages of Docker.

Introduction to Advantages of Docker

The benefits of Docker depend on two angles, the first is the decrease in CapEx and the subsequent one is the decrease in OpEx. Here CapEx implies Capital Expenditure and Opex implies Operation Expenditure. We should comprehend the main viewpoint that is the decrease in CapEx. To see how Docker diminishes CapEx, we need to comprehend various sorts of organizations.

Types of Docker

Below are the types of docker:

  1. Traditional Deployment
  2. Virtualized Deployment
  3. Container Deployment

1. Conventional Deployment: In a customary organization, we need to send applications on actual servers and with regards to doing support on the servers, we needed to close down the application. We had the option to use just 20-30% of our IT assets in the customary arrangement.

2. Virtualized Deployment: Then we went into the virtualized organization. Here we can virtualize the actual equipment and can make different virtual machines on it. It is not difficult to do upkeep on actual servers without closing down the application as we can run virtual machines in a group yet we are simply ready to use 40-half of our IT assets.

3. Holder Deployment: This is the time of compartment arrangement and Docker comes into the image now as it is one of the most well-known compartment runtime applications. Here we convey an application as a compartment utilizing pictures. Pictures are extremely lightweight and it shares the host portion that is the reason we never again need out and out VM to run our applications. We can now use 70-80% of our IT assets.

How about we comprehend it with a model, we should accept we have 100 web servers to deal with the web application traffic so we want 100 VMs. The sum of what VMs have their OS that will take some measure of asset, we should accept each VM takes 1 GB of RAM to run its OS so all out it will take 100 GB to run 100 VMs. Assuming we run a similar application as a holder, we never again need out and out OS so we can save the permitting cost of 100 OS and 100 GB of RAM too.

How about we require the second angle that is the decrease in OpEx. Assuming we run applications as a compartment on Docker, we want less HR to work, oversee and screen the IT framework and it will straightforwardly affect our functional consumption since we can computerize the greater part of the errands and it has the self-mending capacity with the goal that it can recuperate itself consequently.

Advantages of Docker

The following are the unmistakable benefits of Docker:

  1. Quicker is an ideal opportunity to showcase
  2. Engineer Productivity
  3. Organization speed
  4. IT foundation decrease
  5. IT functional proficiency
  6. The quicker issue to goal
  7. Compactness

1. Faster Time to Market

Business is evolving quickly. We really want an apparatus that can meet the business prerequisite at that speed. Here Docker compartment assists with conveying another form of the product with added highlights into creation effectively and with less human connection as we can incorporate Docker with CI/CD pipeline apparatuses like Jenkins. We can without much of a stretch rollback the sending if the fresher variant has any bug or something like that. We can without much of a stretch carry out the Canary test in Docker. In the Canary test, we carry out a more current form of the product into creation for few clients just and assuming everything looks great we gradually send the more up to date form of the product into the creation for all.

2. Developer Productivity

Developer productivity is, quite simply, how productive a developer is in any given timeframe/metric. A company would create objectives/metrics they want to track (for example, bugs fixed and code reviews done) and get a baseline of what’s acceptable. Then, developers would be assessed based on those results to get a good gauge on their productivity. If Ian and Mark are deploying 5 times per day, why is Steve only deploying 3 times? Could there be inefficient processes at the company level, behaviors that could be addressed, or productivity tools that could be implemented to help Steve?

In addition to these metrics, there are multiple ways you can measure a software developer’s productivity by employing different frameworks – for example, one could use the SPACE framework, which we’ll go over below, or one could use OKRs.

3. Deployment Velocity

Docker assists with expanding organization speed from months to weeks. We can undoubtedly send new code to the creation by coordinating it to CI/CD.

4. IT Infrastructure Reduction

As talked about over, the containerized application involves less memory when contrasted with virtual machines. Assuming we take an illustration of ISO picture of Ubuntu it is around 4 GB in size anyway Ubuntu Docker picture is around 60 MB in size that far lesser than ISO picture. It is truly lightweight and uses less assets to run subsequently lessens IT.

5. IT Operational Efficiency

We can utilize docker-create to convey a full-stack application that incorporates every one of our administrations that are expected to fire up a functioning application. It is likewise called microservices where application parts are inexactly coupled to one another. We can undoubtedly increase or down any administrations according to our necessities. Docker utilizes actual servers effectively by appropriating the heap similarly. Docker generally checks for wanted state design and matches the current arrangement and on the off chance that the ideal setup doesn't match the current arrangement, Docker will consequently increase or scale down the compartments. It makes IT tasks.

6. Faster Issue Resolution

As talked about before, Docker has a self-mending ability. It attempts to restart the compartment in the event that the holder isn't reacting and it neglects to do as such it will simply annihilate the holder and make another one for us. So assuming there is an issue we can resolve it rapidly to meet the business prerequisite. There is no much investigating.

7. Portability

Docker pictures are compact as it typifies all that is expected to run an application. It implies assuming that it is running on a test climate, it will run on a creation climate or any open cloud or any OS, just it needs Docker to be introduced on the framework on which we need to run.


Docker enjoys many benefits anyway we can't move every one of our responsibilities to Docker. It is additionally not a trade for virtual machines as both enjoy their own benefits. We want designers who can re-compose or make adjustments to existing code to make the application viable with Docker.
