What is a CDN and How Does It Improve Speed?

In today's digital world, every website owner wants his site to load fast and users to have a good experience. If a website is slow, visitors leave it quickly, which affects both traffic and business. The solution to this problem is CDN (Content Delivery Network) . But many people still do not understand what CDN is and how it increases the speed of our website. In this blog, we will learn step by step what CDN is, how it works and why it is important for modern websites. What is CDN? The full form of CDN is Content Delivery Network . It is a distributed network in which servers are spread across the world. These servers store copies of your website's content (such as images, videos, CSS files, JavaScript files, PDFs, etc.). When a user opens your site, the content is delivered to him from the nearest server. This makes the site load faster because the data does not travel from a far-off server. How does a CDN work? The working of a CDN is simple but the concept is powe...

How Can a Scalable Microservices Architecture Be Constructed?

1. Decoupling Design

To prevent bottlenecks, make sure every microservice runs independently and minimizes dependencies.


2. Adopt an API-First Perspective

To enable services to interact effectively and develop without causing disruptions, use well-defined APIs.

3. Put Auto-Scaling in Place

To automatically scale services based on demand, use orchestration tools like Kubernetes or cloud-native features.


4. Apply Containerization

Use containers (like Docker) to deploy services so that scaling is easier and consistency is maintained across environments.

5. Use Architecture Driven by Events

Incorporate event-based asynchronous communication to improve responsiveness and service decoupling.


6. Make Configuration Management Centralized

For consistency across services, manage configurations centrally using tools such as Consul or Spring Cloud Config.

7. Observe and Record Frequently

Use centralized logging and monitoring (Prometheus, ELK stack, etc.) to preserve performance and obtain insights.


8. Assure Tolerance of Faults

To handle service interruptions politely, build in failsafe measures such as circuit breakers and retries.

9. Enhance Database Access

For each microservice, use a different database, and select the appropriate kind (SQL/NoSQL) based on the requirements of the service.

10. Give security top priority

To safeguard services, use security best practices like identity management, encryption, and API gateways.



Using this method will assist you in creating a microservices architecture that will grow with your needs.

How to Implement a Robust Data Backup Strategy?

Putting in place a robust data backup plan is essential to safeguarding your company against data loss brought on by hacker attacks, system malfunctions, or human error. Here's how to put together a reliable backup plan: 1. Determine Vital Information Determine which data is most important for business operations first. Give important intellectual property, financial records, and customer records top priority. https://globalclassified.net/0/posts/3-Services/24-IT/2402359-setup-brother-com.html https://globalclassified.net/0/posts/3-Services/24-IT/2402370-setup-brother-com.html 2. Apply the 3-2-1 Guideline Use the 3-2-1 backup strategy: store two copies of your data on various types of storage, maintain one copy off-site or in the cloud, and maintain three copies of your data (two backups and your production data). 3. Put Backup Procedures in Motion Reduce human error and guarantee consistency by automating backups. Based on the criticality of the data, schedule regular backups to h...

What is two-factor authentication?

Image
The Protection of Your Digital Life with Two-Factor Authentication (2FA) Taking proactive measures to protect our online accounts is crucial in today's increasingly digital environment, when our private information is always in danger. A strong security feature that provides an additional degree of protection, two-factor authentication (2FA) makes it much more difficult for unauthorized users to access your accounts.  Two-factor authentication: what is it? Two forms of identification are needed to confirm your identity as part of the 2FA security process. This implies that a second factor is still required to access your account even if someone knows your password. You may have something, know something, or be something as this second aspect.  Typical 2FA Techniques 1. TOTP, or time-based one-time password: How it operates: Every 30 seconds, a unique code is generated via a time-based code generator software on your phone, such as Authy or Google Authenticator.  Benefits ...
