Building a Robust Infrastructure: Unleashing the Power of 3-Tier Architecture

Building a Robust Infrastructure: Unleashing the Power of 3-Tier Architecture


When it comes to designing infrastructure solutions, my go-to approach is the concept of 3-Tier Architecture. In this blog post, we will delve into the core principles of 3-Tier Architecture and how it intertwines redundancy, security, and reliability into a cohesive system. By understanding these key components, we can create robust and scalable infrastructure solutions that withstand the challenges of modern technology. Let's explore the power of 3-Tier Architecture and its impact on site reliability engineering and shared nothing architecture.

1. Redundancy - Embracing "Dissimilar Redundancy"

In 3-Tier Architecture, redundancy plays a vital role in ensuring system resilience. By implementing "dissimilar redundancy," we can support multiple operating systems and applications within a single architecture. This approach provides flexibility, allowing us to optimize each tier for specific tasks and technologies. With dissimilar redundancy, we enhance fault tolerance, minimize single points of failure, and ensure seamless operation even in the face of unexpected challenges.

2. Security - Three Layers of Defense

Security is a paramount concern in any infrastructure solution. Within the realm of 3-Tier Architecture, we can implement three layers of defense to fortify our system.

a) "All base are belong to us": Adopting a zero-trust approach, we assume that no component within the architecture can be inherently trusted. By implementing strict access controls, strong authentication mechanisms, and encryption protocols, we establish a secure foundation for our infrastructure.

b) Zero Trust: In the spirit of zero trust, we meticulously verify and validate every interaction within the system, regardless of its origin. By implementing granular access controls, auditing mechanisms, and intrusion detection systems, we create a secure environment where trust is earned through continuous verification.

c) OpenSCAP: OpenSCAP (Open Security Content Automation Protocol) provides a standardized approach to assessing, monitoring, and enforcing security compliance within our architecture. By leveraging OpenSCAP, we ensure that our infrastructure adheres to industry best practices and meets regulatory requirements, thereby minimizing vulnerabilities and mitigating security risks.

3. Reliability - High Availability with Clustering

In the pursuit of reliability, we employ high availability (HA) techniques through clustering. By implementing clustering, we can achieve various configurations, such as active-passive (standby), all nodes as masters (elected by election), or master-slave active-ready standby. These configurations enable seamless failover, load balancing, and data replication, ensuring uninterrupted service even in the event of hardware or software failures. Clustering empowers our infrastructure to withstand high traffic volumes, distribute workloads efficiently, and provide a seamless user experience.

4. Site Reliability Engineering (SRE) and Shared Nothing Architecture

To maximize the efficiency and resilience of our infrastructure, we align our operations team with site reliability engineering (SRE) principles. SRE emphasizes collaboration between development and operations, focusing on building and maintaining highly reliable systems. By embracing shared nothing architecture, where each component is self-contained and independent, we minimize dependencies and create a fault-tolerant ecosystem.


By embracing the power of 3-Tier Architecture, with its focus on redundancy, security, and reliability, we can build infrastructure solutions that stand the test of time. Through dissimilar redundancy, three layers of defense, clustering, and adherence to SRE principles, we create a robust foundation that can withstand the challenges of the modern technological landscape. Let's leverage the strength of 3-Tier Architecture to build reliable, secure, and scalable infrastructure solutions that propel our organizations forward.

Remember, in the realm of infrastructure, the power of 3-Tier Architecture lies in its ability to integrate redundancy, security, and reliability seamlessly


My Idea and AI :


ChatGPT: Can you write this for a blog?

When asked about my "baseline" in designing infrastructure solutions, I build with the concept of a 3-Tier Architecture. You can read more about it here.

I focus on the following 3 things that are tightly integrated with each other (All parts are One):

A) Redundancy - With "Dissimilar Redundancy"
- The ability to support multiple OSes and applications in a single architecture.

B) Security - Enable 3 layers of defense for 3-Tier Architecture.
- "All base are belong to us"
- Zero trust
- OpenSCAP

C) Reliability - High availability (HA) with Clustering.
- Active Passive (standby) / or All are Master (by election nodes) / or Master Slave active ready standby.

Google Bard :  Can you translate this  from malay to english and write it like an english teacher?

Apabila ditanya, apakah "baseline" saya dalam merangka penyelesaian untuk Infra, saya bina dengan konsep 3-Tier Arkitektur. Bacaan panjang tentangnya boleh rujuk ini.

Dan saya fokus kepada 3 perkara berikut yang dikait ketat (integrasi) antara satu sama lain (Semua bahagian adalah Satu) :-

A) Redundancy - Dengan "Dissimilar Redundancy"
- Kemampuan untuk menyokong Pelbagai OS dan aplikasi dalam satu Arkitektur.

B) Security - Aktifkan 3 lapis pertahanan untuk 3-Tier Arkitektur.
- "All base are belong to us"
- Zero trust
- OpenSCAP

C) Reliability - High availability (HA) dengan Clustering.
- Active Passive (standby) / atau All are Master (by election nodes) /atau Master Slave active ready standby.
