Migrating From Redis to Valkey Serverless

The article recounts an experience of traffic doubling for the author's Redis nodes exceeding bandwidth allowance and subsequently putting their service down for almost an hour until the source of the issue could be addressed.
After the incident, the author decided to switch to Elasticache Serverless, which is Valkey Serverless. Valkey is an open-source project that AWS, among others, has been contributing to. It aims to keep Redis compatibility while enhancing overall functionality and performance.
Valkey is offered in both cluster and serverless variants. The serverless variant is billed by Storage and ECPU (ElastiCache Processing Units) and can become very expensive depending on workload. However, if traffic suddenly changes, the serverless variant can abstract cluster managing and sizing.
The author reports that the serverless variant of Elasticache Valkey scales seamlessly without observing throttles, when traffic doubles.
The article suggests that before switching to Elasticache Serverless, careful workload analysis is required, as certain workload characteristics may not be suitable for it.
The article recommends AWS documentation reads, the use of AWS's pricing calculator, and double-checking security group rules, to ensure smooth integration.
The article concludes by stating that Elasticache Valkey Serverless should be considered as a possible solution for elastic scaling issues experienced by similar service structures.

AWS Serverless: Understanding and Managing Lambda Recursive Loops for Event-Driven Architectures using AWS SAM!

This article demonstrates how to validate a Lambda Recursive Loop Configuration using AWS SAM for managing event-driven architectures.
A Lambda recursive loop scenario is created to showcase the configurations that help detect and prevent such loops in an event-driven architecture.
The Lambda recursive loop refers to a scenario where a Lambda function is invoked recursively, creating a kind of infinite loop. It's similar to a do-while loop without an exit condition.
AWS started supporting Lambda recursive loop configurations in July 2023, enabling the detection and prevention of recursive loops in your Lambda functions.
This feature is enabled by default and supported by services like Amazon Simple Queue Service (SQS), Amazon Simple Notification Service (SNS), and Amazon Simple Storage Service (S3).
Configurations like budget monitoring, function invocation monitoring, and CloudWatch alarms can be used as alternative guardrails when disabling the Lambda recursive loop feature.
The deployment of SQS queue and lambda function event mapping is demonstrated using AWS SAM.
Custom monitoring for recursive invocations can be set up by observing the Lambda function invocations, specifically the RecursiveInvocationsDropped metric.
AWS will send an email and notification via the Health Dashboard when a recursive loop is detected.
To avoid resource usage, the Lambda function, SQS Queue, and any new roles created during the process must be deleted once the exercise is completed.

From Local to Cloud: A Beginner’s Journey with Git and Cloud Architecture

Version control helps manage and track changes to code over time, enabling retrieval of earlier versions and tracking who made changes to code. Collaboration enables multiple people to work on the same project without overwriting each other's work. Git is a distributed version control system designed to handle projects of any size with speed and efficiency by allowing every developer to have a full history of the codebase and facilitating powerful branching and merging. System design requires a systematic approach to architecting and building systems, considering infrastructure, hardware, software and data. High availability ensures operational performance, making sure the system is always up. Fault tolerance prevents downtime and service interruptions by immediately taking over when a component fails and requires no manual intervention.
The role of version control is to track changes in projects evolution, bug fixing, and understanding who made changes, when and why.
In Git, repository is a database storing full history of the projects files and revisions; and commit is a snapshot of files at a particular point in time, including a message describing the changes. Branch is a parallel version of the repository created to develop features, fix bugs or experiment new ideas.
CVCS and DVCS are Centralized and Distributed Version Control Systems respectively. CVCS contains all version files in a single server, while DVCS allows each user to have a fully-fledged repository on their local machine.
Writing clear and descriptive commit messages, committing changes frequently, and effective branching strategy all help in Git version control.
Cloud architecture offers the infrastructure to deploy, scale, and manage applications. High availability by ensuring operational performance and fault tolerance by preventing downtime are essentials in cloud architecture.
Load balancing, which distributes incoming traffic across multiple servers, is crucial in ensuring the smooth running of applications. High availability focuses on minimizing downtime for maintenance and all unexpected failures while fault tolerance is designed to prevent downtime and service interruptions.
Mastering Git and cloud architecture is essential for software development in transforming from local to cloud.
System design requires thinking of everything in the infrastructure, hardware, software, and data storage, including how data is stored and secured.
Horizontal Scaling involves increasing the number of machines in a system, allowing for limitless growth, high availability, and fault tolerance. Vertical Scaling, on the other hand, involves increasing the processing power of a single machine such as RAM, CPU, etc.

Getting Started with DynamoDB and Global Secondary Indexes

Amazon DynamoDB stores data in the form of documents (key-value pair), which provides greater flexibility and scalability.
When creating a table in DynamoDB, you need to define a partition key and optionally a sort key.
DynamoDB uses the partition key value as input to an internal hash function.
This mechanism eliminates the need to scan the entire table when performing operations.
The Query operation is used when you want to fetch items based on a specific partition key value.
The Scan operation in DynamoDB reads every item in a table or secondary index.
Global Secondary Index (GSI) in DynamoDB is a secondary index that enables querying a table using non-primary key attributes.
It’s important to note that GSIs operate on an eventually consistent model.
GSIs storage is billed separately from the main table, with costs depending on the size of the indexed data and the attributes included in the index.
By adding GSI on 'UserName' we can make the retrieve operation more efficient.

Starting with Self-Hosting

The author shares their experience and enthusiasm for self-hosting, including details of their own setup and the advantages of hosting their own utilities and services.
With a physical server, they can easily handle hundreds of requests per second without breaking a sweat and have control over their privacy with some security measures in place.
Hosting a network-attached storage (NAS) for backups is one of the author's primary uses, while the more they learn, the more benefits there are in store, including hosting their own services for the world to use.
The author mentions a few ways to optimize a DIY tower server, including playing with the ARR Stack and running a VPN (Virtual Private Network), which is useful when they're away from their server for long stretches of time.
Hosting their own offsite services allows the author to offload their devices' workload and automate some tasks and receive the results later. Self-hosting projects on 'bare metal' is an invigorating and enlightening experience.
While the initial investment might be high, the costs of storing terabytes of data, VPN, among other services are significantly lower compared to the VPS costs. There may also be a time investment associated with making everything work initially.
Additionally, confidentiality and privacy are paramount when hosting your own services, and the author believes users should aim for the best security measures available to them.
Finally, the author aims to host services for themselves and to self-host services to the internet, but before that can happen, they need to work on foundational matters such as security and segregation for 'management' and 'services.'
This article would be helpful for readers interested in the technical and cost advantages of hosting their own data storage, services, and utilities and how they can get started themselves.
Readers can benefit from exploring the glossary of technical terms for a better understanding of the concepts included in this article.

Nvidia says the RTX 5070 is as fast as the RTX 4090 — let’s look at the specs

Nvidia recently announced their new RTX 50-series GPUs claiming double the performance with the RTX 5090 and saying that the more modest RTX 5070 could equal the performance of the last-generation RTX 4090.
The RTX 4090 debuted in October 2022 and has an eye-watering price tag of $1,600 and is sold out almost everywhere. In contrast, the RTX 5070 will be released in late February with a suggested retail price of $550.
On paper, the RTX 5070 has a third less memory bandwidth, half the physical memory, and barely a third of the CUDA core count with comparable boost clock speeds than the RTX 4090.
However, Nvidia’s claims largely center around the enhanced support for AI-driven upscaling using the latest generation of Tensor cores, with the RTX 5070 featuring multi-frame generation.
Until testing is done, it is unclear how good this next-generation card is or how it stacks up against the RTX 4090, but Nvidia’s slides suggest that the RTX 5070 may be less than 20% faster than the RTX 4070.
Numerous factors, including DLSS 4 support and its new architecture, process node, and DLSS-heavy marketing, make it challenging to say for sure how good the RTX 5070 really is.
It seems unlikely that the RTX 5070 can match the RTX 4090's performance in most games, and heavy multi-frame generation can introduce latency issues and visual artifacts unlikely to be loved by everyone.
Nonetheless, the RTX 5070's reduced power usage and new architecture might enable it to close the performance gap with the RTX 4090, making it appropriate for small form-factor gaming PCs.
If you're currently using the RTX 4090, it is unlikely that the RTX 5070 will measure up to its performance, so beware of the FOMO of a new generation.
Wait for real-world testing to settle this performance debate until the RTX 5070 is released next month.
