Design and Implement a High-Performance, Distributed Web Hosting Platform for Growing Digital Services

The client operates a digital platform that is encountering limitations with its existing monolithic hosting architecture, leading to difficulties in handling increased user demand, higher traffic volumes, and a growing number of client websites. The old infrastructure cannot sustain high load performance, ensure high availability, or support future growth without significant downtimes and operational risks.

A rapidly expanding online service provider offering website hosting, customizable website building, or digital content platforms, requiring scalable and highly available infrastructure.

• Develop a distributed, high-performance platform capable of handling increased user traffic and website hosting demands.
• Ensure system high availability with an SLA of 99.95% uptime.
• Implement scalable architecture facilitating smooth growth and future expansion.
• Achieve near-zero downtime during system updates, failures, or unexpected events.
• Enhance system monitoring and automated recovery processes to mitigate downtime risks.

• Distributed architecture utilizing multiple physical hosts to support load balancing and fault tolerance.
• High-availability shared storage system with data replication and transparent failover mechanisms.
• Scalable database clusters with replication, monitored via load balancers for seamless master failover.
• Application clustering based on HTTP reverse proxy, web servers, and session replication to ensure uninterrupted user sessions.
• Zero-downtime deployment processes enabling smooth updates without interrupting active sessions.
• System monitoring tools for failure detection and automatic recovery, such as an integrated monitoring and alert system.

• Database monitoring and failover management systems
• Load balancer integration with web server clusters
• Automated deployment and version control tools
• Failure detection and recovery automation tools

• System must support high load scenarios with scalable resource allocation
• Achieve SLA of 99.95% uptime
• Minimize system downtime during updates or failures
• Implement fast recovery times from outages
• Ensure data consistency and integrity across replicated storage and databases

The new platform is expected to support increased client demand and user traffic, leading to enhanced system performance under high load conditions. It will ensure near-zero downtime, boosting customer satisfaction and trust. The scalable architecture will facilitate seamless future growth, improving operational efficiency and reducing maintenance risks associated with system failures or updates.
