We started with the classic load balancer for its simplicity but as our needs evolved, we migrated to an Application Load Balancer (ALB) due to its advanced routing features. The ALB allowed us to route requests based on content type which was crucial for our microservices architecture. We also implemented auto-scaling to handle peak loads and ensure high availability.

As an AWS Cloud Devops Engineer, a significant part of your job is to ensure system resilience. When a company’s operations are heavily reliant on cloud services, any downtime can be costly and disruptive. Therefore, your interviewer wants to see that you understand how to build and maintain highly available and fault-tolerant systems in the AWS environment.

Do we need to open outbound port 80/443 on the load balancer’s security group to allow return traffic from the server?

Application load balancing is mostly used when there is a need to route traffic to multiple services. A Virtual Machine (VM) is a software-based emulation of a computer system that allows multiple programs to be run on a computer as if they each had access to the entire computer. VMs provide a completely virtual environment, including virtualized hardware, operating system, storage, and network resources, that are isolated from the underlying physical infrastructure.

Similarly, a digital company should have intense focus on Development Operations (DevOps). Think of your company’s DevOps process as the supply chain responsible for making sure your product features ship to your customers. Tactically, DevOps means ensuring that code is written, well managed, tested, and deployed in a reliable and repeatable way. Disruptions or holes in your company’s DevOps procedures will inevitably cause downtime or service degradation for your customers.

Autoscaling, an integral feature of AWS, allows systems to automatically adjust capacity to maintain steady, predictable performance at the lowest possible cost. By asking this question, hiring managers want to gauge not just your familiarity with AWS services, but also your strategic approach to managing resources and ensuring optimal system performance.

Packing switching simply refers to dividing each internet server into multiple internet servers. The supporting devices of the internet would be enough to make a better and reliable sharing of internet among plenty of computers. Multiple availability zones will surely have at least one AWS region for showing much better and improved functioning to the clients within some faster time. At the highest or grand levels of AWS infrastructure, it will be made up of numerous regions all across the globe and this entire happening can be called or known as an AWS region. Every AWS region will consist of plenty of AWS availability zones especially in those areas where the AWS availability zones are located. It is actually a collection of physical AWS infrastructures or its regions present all across the world.

Opting to host all data and instances in a single availability zone may lead to unavailability if that zone experiences a failure. AWS Identity and Access Management (IAM) is a web service designed to enable secure control over access to AWS resources. IAM allows for centralized management of permissions, regulating users’ access to specific AWS resources. It is utilized to govern the authentication (sign-in) and authorization (permissions) of individuals, determining their ability to use various resources.
