Cloud Migration and Infrastructure Optimization from PaaS to IaaS for Enhanced Scalability and Control

The client’s existing cloud hosting environment, based on a Platform-as-a-Service (PaaS), is increasingly inadequate to meet growing traffic, performance, and operational control requirements. Limitations include constrained server configuration, resource caps leading to performance bottlenecks, reduced control over environment setups, rising costs with scaling, and reliability concerns due to environment management restrictions.

A mid-sized business services company with a growing web application facing scalability, performance, and control limitations on their current PaaS environment.

• Improve application performance and resource utilization through scalable infrastructure configurations.
• Enhance operational control and flexibility by enabling full environment access and customization.
• Reduce hosting costs by optimizing resource allocation and adopting a pay-per-use cloud model.
• Increase application reliability and uptime by leveraging the cloud provider's proven service level commitments.
• Implement containerization for rapid deployment, testing, and environment consistency.
• Ensure support for complex software dependencies and environment upgrades with minimal downtime.

• Containerized deployment environment using Docker, supporting rapid packaging and portability.
• Deployment automation on cloud-managed services that support Docker, such as Elastic Beanstalk or equivalent platforms.
• Configurable server instances with various CPU and memory profiles to match application load demands.
• Full root or admin access to manage environment configurations and software dependencies.
• Monitoring and cost management tools to optimize resource usage and operational costs.
• Automated environment setup processes for quick provisioning of test, staging, and production environments.

• Monitoring and performance analytics tools
• Cost and resource management dashboards
• Security scanning tools for container vulnerability assessment
• Automated testing and deployment systems

• Scalability: Support for rapid scaling of resources to handle increasing user traffic.
• Performance: Ensuring minimal latency and optimal resource utilization.
• Reliability: Achieve high uptime with cloud provider SLAs.
• Security: Enforce security best practices, including vulnerability scanning and environment isolation.
• Cost-efficiency: Optimize resource allocation to reduce monthly hosting expenses.

By migrating to a flexible IaaS cloud environment with containerization, the client aims to enhance application performance and scalability, achieve operational control and customization, reduce ongoing hosting costs by approximately 20-25%, and improve reliability and uptime, thereby supporting business growth and delivering a better user experience.
