Most business managers get confused between CloudOps and DevOps easily. And it is a way too common problem so here we are drawing a line between CloudOps and DevOps that can help the business managers understand the basic difference between CloudOps and DevOps.
As the name proposes, DevOps is a mix of ”Development” and ”Operations”, and depicting it as “specialized deft” appears to be shockingly exact. A bunch of practices and processes assist associations with making a spry, cooperative climate that unites software development, IT tasks, and quality designing to fulfill the basic business operations such as:

Nowadays, LoadBalancing is one of the basic needs for the application systems to perform optimally while considering some important factors like- scalability and high availability. Every cloud is providing LBaaS (LoadBalancing as a Service) as an offering so the consumers don’t have to worry about the setup and management of load-balancers by themselves.
But it’s not like that cloud is offering a single type of load balancer for every use case because for different use-case we require a different type of load balancer. For example- we have different load-balancers for Layer4 and Layer7 level traffic.
Recently AWS had a new family member in their load-balancer family and they named it “Gateway Load Balancer“. So gateway load-balancer is a load-balancing service provided by AWS to send traffic to the different appliances, applications, firewalls, etc. that are not part of the current VPC.

MongoDB is a popular NoSQL database that supports large as well as small size of datasets. Just like any other database standalone setup, MongoDB is straightforward but we have to make a replicated or shared cluster of MongoDB, and there we have certain complications. Especially if we are doing these kinds of setups in orchestration tools like Kubernetes.
There is a lot of complexity in setting up MongoDB on Kubernetes that people(including me) have faced for a long time which I would like to highlight:-

- Standalone setup is pretty straightforward but for replicated and sharded clusters additional mongo configurations are required.
- In the replicated scenario, separate configurations need to be managed for the leader and follower.
- Monitoring and access management of MongoDB inside Kubernetes is a little tricky part to handle.
Let’s start with a scenario, whenever any application builds, we generally do have 3 environments on the basis of resources – dev for developers resources, test for testers resources, and prod for production resources. Likewise, we used to have a separate IT-Operational Team having strategies to maintain their environment resources. It was very time-consuming and many human resources were required.
We are in the microservices era where we follow the DevOps Methodology. The DevOps Team brings all the environment and strategies to maintain resources in one go. Resources are the ones who decide the behavior of your applications. We can apply the criteria to resources, so how can our application behave? To do this we can give the name to our resources, we can give the resources quota to the application, and can give resource ranges to the application.

We all have used IAM credentials to access our S3 buckets. But it’s not a very safe or recommended practice to keep our Access keys and Secrets stored in a server or hard code them in our codebase.
Even if we have to use keys, we must have some mechanism in place to rotate the keys very frequently (eg: using Hashicorp Vault). Another widely adopted method is to use IAM roles attached on the EC2 instance or the AWS service accessing the bucket.
But, what if we need access to the bucket from an on-premise Data Center where we can not attach an IAM role?
Yes, we can obviously use IAM credentials and secret tokens with the rotating mechanism. But setting up the key rotation mechanism itself could be another overhead if we do not have one already in place. What if we do not require keys or roles without making the bucket public?

In this blog, I will make an attempt to cater to this problem with another alternate and easy solution.
