VPC Interface Endpoint vs. Gateway Endpoint in AWS

What is a VPC Endpoint? With a VPC endpoint, you can establish a private connection to specific AWS services and VPC endpoint services through AWS PrivateLink. It eliminates the need for public IP addresses for communication between these services and your Amazon VPC instances. Furthermore, a secure connection is maintained since no information leaves the Amazon network while traveling between your Amazon VPC and the service. VPC endpoints are virtual devices that enable communication [...]

Switching Your Spot EC2 Instance to a Reserved EC2 Instance

Amazon Elastic Compute Cloud (EC2) is a cloud computing service that instantly provides flexible and scalable resources to deploy virtual servers, called instances. While Spot Instances can save you a significant amount of money, especially for short-lived workloads, there may come a time when you need a more predictable pricing model. This is where Reserved Instances (RIs) come in handy. In this article, we'll explain the reasons for switching from a Spot Instance to [...]

Securing Application Logs with Amazon Comprehend

Security is one of the more overlooked aspects that many fall victim to when designing the architecture of applications. Partnering this lack of security priority with the increasing value of personal user data, security breaches become one of the certain ways for companies to lose user trust, face legal charges, and, in the long run, fail. Various governments developed data compliance laws to set minimum guidelines for security in data handling by data stakeholders. [...]
