Default Encryption for new S3 Objects

Amazon Web Services (AWS) recently announced a new feature for its Simple Storage Service (S3). This feature encrypts all new objects by default. S3 automatically applies server-side encryption (SSE-S3) for each new object. S3 buckets that do not use default encryption will use SSE-S3 as the default encryption option. Existing buckets currently using S3 default encryption will not change. You can always opt-in for different encryption options (SSE-KMS, SSE-C).

Before default encryption, users had to manually verify that encryption was enabled for the S3 bucket and make sure that it stayed that way. This could be time-consuming and prone to mistakes, as many security issues were related to S3 public access.

There are several benefits to using default encryption for S3. First and foremost, it ensures that all objects stored in an S3 bucket are encrypted, which is important for data security and compliance with regulatory standards such as the EU’s General Data Protection Regulation (GDPR) and the Payment Card Industry Data Security Standard (PCI DSS).

AWS offers several options for default encryption, including Amazon S3-Managed Keys (SSE-S3), AWS Key Management Service (SSE-KMS), and customer-provided keys (SSE-C). SSE-S3 uses keys managed by AWS to encrypt objects, while SSE-KMS allows users to manage their own keys and gives them the ability to audit and control access to their keys. SSE-C allows users to provide their own keys for encryption, which can be useful for organizations with strict key management policies.

Overall, the new default encryption feature for AWS S3 is a welcome addition that makes it easier for users to ensure the security of their data. It can save time and reduce the risk of mistakes, while also improving the security of data in transit and at rest.

Concurrency With Boto3

In a very simple sense, it does this by having an event loop execute a collection of tasks, with a key difference being that each task chooses when to yield control back to the event loop. Asyncio is a good fit for IO-bound and high-level structured network code. Boto3 (AWS Python SDK) falls into this category. A lot of existing libraries are not ready to be used with asyncio out of the box. They may block, or depend on concurrency features not available through the module. It’s still possible to use those libraries in an application based on asyncio by using an executor from concurrent.futures to run the code either in a separate thread or a separate process. The run_in_executor() method of the event...

AWS Lambda Function URLs

In this tutorial, we will explore AWS Lambda Function URLs , which are the endpoints that allow you to invoke your Lambda functions. AWS Lambda Function URLs are unique HTTP endpoints that you can create using AWS Console, SDK or any other IaC tool. These URLs are used to trigger your Lambda function, and they can be integrated with a variety of workloads. Function URLs are dual stack-enabled, supporting IPv4 and IPv6. After you configure a function URL for your function, you can invoke your function through its HTTP(S) endpoint via a web browser, curl, Postman, or any HTTP client. Once you create ...

DNS Failover with Route53

To showcase this feature, we are going to deploy an application, which we built in this blog post , to two different AWS regions. We are also going to set active-passive failover in Route53, then we will remove the application from one region and we’ll observe how DNS queries will react to the changes. AWS describes the failover scenarios in 3 different categories Active-passive : Route 53 actively returns a primary resource. In case of failure, Route 53 returns the backup resource. Configured using a failover policy. Active-active : Route 53 actively returns more than one resource. In case of failure...
