Interview Questions on AWS Networking: VPC, Load Balancers, and Auto Scaling

AWS VPC (Virtual Private Cloud) is a logically isolated network within the AWS cloud where you can launch your AWS resources securely.
A stateful firewall keeps track of the state of active connections, automatically allowing return traffic.
Traffic in a VPC flows through the following components: Route Tables, Internet Gateway (IGW), Network ACLs and Security Groups.
For a 2-tier architecture, distribute subnets across multiple Availability Zones for redundancy.
To restrict outbound internet access for a specific subnet, remove the route pointing to 0.0.0.0/0 (default route) in the subnet's route table.
Use a NAT Gateway to allow instances in a private subnet to access the internet.
A Load Balancer distributes incoming traffic across multiple targets, such as EC2 instances, containers or IP addresses, ensuring better fault tolerance and high availability.
ASGs automatically adjust the number of EC2 instances based on demand using scaling policies and health checks. This helps save costs.
To create a scalable architecture, create a VPC with public and private subnets, place a Load Balancer in the public subnet, deploy application servers in the private subnets using an Auto Scaling Group.
While Security Groups control access at the instance level, NACLs provide an additional layer of subnet-level security.

Kubernetes 1.32: Moving Volume Group Snapshots to Beta

Kubernetes 1.32 has moved the support of volume group snapshots from alpha to beta.
This support relies on a set of extension APIs for group snapshots.
Volume group snapshots are used to create a crash-consistent snapshot of multiple volumes.
This new feature is only supported for CSI volume drivers
The feature aims to restore a set of snapshots to new volumes and recover your workload
Volume groups are defined by a label selector that groups multiple PersistentVolumeClaims for snapshotting.
Three API kinds are defined as CRDs that are used for managing snapshots.
The VolumeGroupSnapshot feature in CSI spec moved to GA in the v1.11.0 release.
The logic to dynamically create the VolumeGroupSnapshot and its corresponding individual VolumeSnapshot and VolumeSnapshotContent objects are moved from CSI snapshotter to the common snapshot-controller.
The beta implementation of volume group snapshots for Kubernetes has some limitations, including not supporting the reverting of an existing PVC to an earlier state represented by a snapshot.

Why does improving Engineering Performance feel broken?

Improving engineering performance is essential for all teams. Engineering performance review is to analyze how teams, systems, and workflows efficiently contribute to delivering software.
Engineering reviews found invaluable to achieve Continuous Improvement, Accountability, Alignment, Celebrating Wins, and Visibility.
At scale, processes that worked informally begin to break down, creating frustrations for both leadership and teams. What once enabled quick collaboration now feels like a painful exercise in the blame game or either an exercise in vanity metrics.
Engineering reviews come up short because the process itself feels disconnected from the teams it aims to serve, and are painful and unfair out of the box, rely on sporadic code instrumentation or custom database queries.
Engineering leaders can transform reviews into a collaborative, empowering process by treating engineering teams like customers and engaging as co-creators.
Propose frameworks, compliance standards, or engineering performance tools as means to an end-not as rigid mandates. Enable a product brief review process.
Engineering performance reviews should not be about hitting abstract benchmarks or generating metrics for leadership’s sake, but should serve as opportunities for teams to uncover bottlenecks, align on priorities, and drive meaningful, systemic change.
In the upcoming article, we will explore frameworks, tools, and real-world examples to help design and execute engineering performance reviews that deliver results—without the pain.

Why Staging Is a Bottleneck for Microservice Testing

Engineering teams adopting microservices architecture have typical CI/CD workflow.
Shared staging environments create bottlenecks which slow down teams and undermine the advantages of microservices.
Bugs from one team can block multiple others due to shared staging environments.
Multiple PRs being merged daily makes it hard to isolate why a test fails.
Multiple teams waiting for their turn to test features in staging delays releases and creates bottlenecks.
Automated tests scheduled for off-peak hours delay feedback loop and productivity.
Shared staging environments lead to slower shipping of features and patches.
Isolated testing eliminates the problems caused by shared environments and enables true continuous delivery.
Platforms like Signadot and other companies have adopted the model of isolated testing.
Isolated testing allows teams to catch issues early in the development cycle, reducing the complexity and cost of fixing bugs later.
