Why Your App is Still Slow After Optimization?

Sat, 30 Aug 2025 12:31:22 +0000

You have optimized your database queries, your API responds in under 100ms, and your CDN is correctly configured. Yet users still report slow load times, and performance monitoring shows latency spikes that appear without explanation.

The issue often lies outside your application or infrastructure. Two core network protocols can directly impact performance. TCP congestion control may make inefficient decisions about how data flows under varying conditions, and BGP routing can send traffic along longer, suboptimal paths across the internet.

Layer 4 vs Layer 7 Load Balancing Explained

Thu, 28 Aug 2025 09:37:04 +0000

When you browse Instagram, stream Netflix, or shop on Amazon, robust load balancing technology works silently in the background, handling millions of simultaneous requests across multiple server. This critical infrastructure component prevents system overloads and ensures consistent user experiences even during traffic spikes.

Load Balancing Fundamentals

Load balancing distributes incoming network traffic across multiple servers to ensure no single server becomes overwhelmed. This improves application responsiveness and availability while preventing server failures. The choice between Layer 4 and Layer 7 load balancing represents a crucial architectural decision with significant implications for performance, security, and functionality.

Ansible vs Terraform

Tue, 02 Apr 2024 20:00:50 +0000

Imagine, As your business grows bigger, setting up and configuring things like servers, databases, and networks becomes a real pain if you do it by hand. Spinning up new servers one by one, copying and pasting commands, and keeping track of everything is super time-consuming and mistakes happen easily. Keeping all your servers configured the same way, installing updates, and deploying new code versions is a nightmare without help.

That’s where tools like Terraform and Ansible come to the rescue. Terraform is awesome at setting up your infrastructure like servers, networks, and databases. Instead of doing everything manually, you write code that describes what you want, and Terraform handles it for you. Need 10 new servers? Terraform gets it done with just a few commands.

How to Test the Accuracy, Risks, and Reliability of LLMs with Deepchecks?

Wed, 27 Dec 2023 12:01:28 +0000

As large language models (LLMs) grow more capable with billions of parameters, validating their responsible behaviour throughout training, testing and deployment lifecycles becomes too complex and essential. The accuracy of a language model refers to how well it’s able to generate relevant, factually correct, and coherent text.

While Pre-deployment testing tends to focus narrowly on metrics like perplexity that reward fluent text generation. However, fluency alone cannot guarantee LLMs behave responsibly when deployed.

Should You Use Open Source Large Language Models?

Sun, 10 Dec 2023 15:34:28 +0000

Large language models (LLMs) powered by artificial intelligence are gaining immense popularity, with over 325,000 models available on Hugging Face. As more models emerge, a key question is whether to use proprietary or open-source LLMs.

What are LLMs and How Do They Differ?

LLMs leverage deep learning and massive datasets to generate human-like text
Proprietary LLMs are owned and controlled by a company
Open-source LLMs are freely accessible for anyone to use and modify
Proprietary models currently tend to be much larger in terms of parameters
However, size isn’t everything - smaller open-source models are rapidly catching up
Community contributions empower the evolution of open-source LLMs

How Do (LLM) Large Language Models Work? Explained

A large language model (LLM) is an AI system trained on extensive text data, designed to produce human-like and intelligent responses.

Monolithic vs Microservices Architecture

Tue, 28 Nov 2023 06:23:11 +0000

As software systems scale in complexity, architects must decide whether a monolithic or microservices architecture is the best choice. This decision greatly impacts system scalability, fault tolerance, ease of development, and more for years to come.

1. Monolithic Architecture

In a monolithic design, all critical application components are combined into a single, tightly integrated unit. The components are heavily dependent on each other and communicate via language-level interfaces. The entire software system scales and is deployed as one. Performance can be greatly optimized via shared state and function calls between components. The data model is enforced in a single database.

DevOps vs SRE vs Platform Engineering

Sun, 26 Nov 2023 06:30:56 +0000

Originally, DevOps, SRE, and Platform Engineering were just new ways of thinking - cultures and philosophies. But over time, they’ve turned into real roles at companies with specific focuses and responsibilities. This profile of job titles can create confusion - What exactly do these roles for? How do they interact and differ?

Of course, all these new job titles can get confusing. DevOps engineer, SRE, and platform engineer - they sound pretty similar, right? But while they’re related in some ways, the work these roles do is also very different.

REST vs. GraphQL: Which API Approach is Right for You?

Sat, 22 Apr 2023 05:34:16 +0000

When it comes to building APIs, two of the most popular approaches are REST and GraphQL. Both REST and GraphQL are used to enable communication between different applications over the internet through APIs. But what are the key differences between the two, and which approach is right for your project? Let’s take a closer look.

What is REST?

REST, or Representational State Transfer, is an architectural style for building APIs that relies on HTTP requests to interact with resources. In a RESTful API, resources are identified by unique URIs (Uniform Resource Identifiers), and clients can make requests to these URIs to retrieve or manipulate the resource.
