During our meetings with clients, our clients want to know about the things that we are doing while implementing their application and they are right! After all, they are the ones who need to use it in the future for their business purposes. However, and nowadays, Docker is Implementing so fast, and become necessary to implement simultaneously with keeping in mind their benefits and different usages. Similar situations often happen during Docker consulting services from 9series and their meetings. We as a web development company think to remove all the doubts of our clients through creating a FAQ about Docker. So, Let’s dive into that part where we answered the most Frequently Questions about Docker Technology!

Now, you are all set to deploy your application or any orchestrated service.
One notable thing is It worked the same whether your application is from a cloud provider, local data center, or hybrid one.
- Should I use microservices or monolith architecture in order to use Docker?

(Pro-tip: as per the trend, we personally suggest to use Microservices Architecture instead of Monolith architecture.)
- Is using Docker slowing down my site?
