Nvidia’s DLSS 4 isn’t what you think it is. Let’s debunk the myths

Nvidia unveiled their new RTX 5090 at CES 2025, which includes DLSS 4 offering over a 4x boost in performance for more than 75 games.
Many are confused about DLSS 4's features, believing it “predicts the future,” instead it uses interpolation to predict interstitial frames between rendered frames.
This tech adds some latency, but this is not much different from DLSS 3. DLSS 4 uses the same frame interpolation technique used by DLSS 3.
DLSS 4 is different from DLSS 3; it uses a complete new transformer model that runs five independent AI models per rendered frame for ray reconstruction and multi-frame generation etc.
DLSS 4 has better preservation of fine details and stability compared to DLSS 3 approach, and all RTX graphics cards will be able to leverage the features that are supported by each generation.
The new transformer models' self-attention allows the DLSS 4 to focus more on highly problematic areas such as thin details with Super Resolution that may show shimmering.
Latency will not be a big issue, as the time between each frame rendered using DLSS technology does not change much.
Nvidia's Reflex 2 is not necessary for DLSS 4, and developers only need to implement the first version of Reflex for DLSS 4 to work.
DLSS 4 has seen a few demonstrations, but it will be interesting to test its real functionality when the next-gen GPUs are launched.
The new interim technology is potentially going to be a game-changer in the AI-driven industry.

Navigating Disaster Recovery in the Digital Age: Choosing the Right Approach – Part 2

Disaster recovery focuses on restoring data and systems after a disruptive event while backups simply preserve data against data loss.
Six factors impact the decision-making process of selecting the right backup and disaster recovery (DR) solution.
The primary goal of backups is to protect against data loss, while DR restores entire systems and applications so that business operations can resume as quickly as possible after a disruptive event.
When designing a backup or disaster recovery (DR) solution, architects must determine whether the client needs a Backup solution, a Disaster Recovery solution, or both to avoid costly misalignments.
AWS-native tools offer seamless integration and a comprehensive suite of tools. Third-party solutions provide advanced capabilities and flexibility, catering to specific use cases like hybrid environments or complex recovery requirements.
Clients rely on architects to present comprehensive and unbiased recommendations. Demonstrating knowledge of both AWS-native and third-party options positions architects as a trusted advisor.
In part three, the remaining four key considerations: RPO/RTO requirements, physical versus virtual servers, scheduling and automation, and the choice between on-premises and cloud restores will be discussed.
Choosing the appropriate tools and processes to meet an organization’s recovery objectives is highly influenced by understanding the trade-offs of the available options.
Finally, overdesigning for backups can be unnecessarily complex and expensive, while underestimating recovery needs can result in prolonged downtime and significant business losses.
Having a clear understanding of the differences between Backup and DR, and evaluating AWS-native versus third-party solutions are foundational factors for an effective backup or DR solution.

AWS Identity Access and Management

AWS Identity and Access Management (IAM) is the foundation of cloud security and plays a pivotal role in managing and securing access to resources.
IAM in AWS is like the game master of a huge RPG—ensuring that each player only gets access to the areas they’re authorized to explore.
IAM plays a critical role in managing and securing access to resources in multi-account environments, which have become prevalent in today's cloud computing ecosystem.
IAM includes users, groups, roles, and policies; which makes it a versatile solution for managing access to AWS resources.
IAM helps in reducing security risks by providing temporary or time-limited access to AWS resources.
With IAM policies, access can be granular and tightly controlled, protecting both the company's and customers’ data.
IAM Identity Center provides a unified solution for centralized user management, simplified access control, enhanced security features, streamlined workflows, and fine-grained permissions.
Netflix, Airbnb, and NASA Jet Propulsion Laboratory are some of the organizations which use IAM for managing access to their cloud resources.
IAM is a must-know concept for anyone starting in cloud computing as it plays a vital role in managing identity and access for cloud resources, ensuring security and compliance.
To learn more about IAM, do check out the official documentation and user guide provided by AWS.

AWS Serverless: How to Create and Use a Lambda Layer via the AWS SAM - Part 2

AWS Serverless Lambda functions can be developed and deployed to AWS Cloud with ease using the Infrastructure as Code (IaC) framework AWS SAM (Serverless Application Model).
Lambda Layer is a way of sharing reusable code and libraries among multiple Lambda functions. The layer makes the size of Lambda function deployment smaller and ensures consistency across functions.
Lambda layers can be used in various scenarios such as shared libraries, custom functions, common configuration, and logging tools.
When using Lambda layers, keep in mind certain constraints such as five layers limit and the maximum size limit of 50 MB compressed per layer.
A Lambda function uses layers by importing modules and calling functions from those modules.
The AWS SAM can facilitate the build, validation, and deployment of Lambda layers and functions to AWS Cloud.
The entire process from creating a Lambda layer to referencing it in a Lambda function and then building and validating can be accomplished using AWS SAM.
After validating the function locally, you can deploy it to the AWS Cloud using the sam deploy command.
To avoid unnecessary resource usage, remember to delete the Lambda function and the Lambda layer.
AWS SAM is an efficient way of testing and debugging Lambda functions before deploying them to the cloud.

How Nvidia is creating a $1.4T data center market in a decade of AI

For more than three decades, x86 architectures dominated computing. Today, general-purpose processing is giving way to specialized accelerators.
We categorize “extreme parallel computing” as the specialized hardware and software for AI training, inference, HPC clusters and advanced analytics.
Nvidia accounts for roughly 25% of the entire data center segment. Our view is that Nvidia will retain that leading share throughout the forecast period — assuming it avoids unforced errors — despite intense competition from hyperscalers, AMD and others.
We have modeled the entire data center market — servers, storage, networking, power, cooling and related infrastructure — from 2019 through 2035. Our research points to a rapid transition away from traditional general-purpose computing toward extreme parallel computing.
We believe the transition from general-purpose, x86, central processing units toward distributed clusters of graphics processing units and specialized accelerators is happening even faster than many anticipated.
InfiniBand emerged as the go-to for ultra-low-latency interconnects. Now, we see that trend permeate hyperscale data centers, with high-performance Ethernet as a dominant standard which will ultimately in our view prove to be the prevailing open network of choice.
Nvidia’s advantage does not hinge on chips alone. Its integration of hardware and software — underpinned by a vast ecosystem — forms a fortress-like moat that is difficult to replicate.
Although competition is strong, none of these players alone threatens Nvidia’s long-term dominance — unless Nvidia makes significant missteps.
The data center — as we have known it — will transform into a distributed, parallel processing fabric where GPUs and specialized accelerators become the norm.
The anticipated shift toward accelerated compute forms the foundation of our bullish stance on data center growth.
