Cloud Platform Resiliency Services for Enterprises

Overview

The core objective of digital transformation for enterprises is to provide services with superior efficiency, performance, availability, and resiliency. The capabilities of the applications and platform include

Consistent experience for global customer base
Continuous monitoring for service levels and user experience
Tracking failures and faster recovery for outage or service disruptions
Ensure business continuity and application resiliency at optimal cost

Infosys Cobalt has a prescriptive approach to build and optimize fault tolerant systems and includes a set of reference architectures, technology partner ecosystem and pre-built solutions as blueprints, code snippets and more.

The solution stack contains:

Reference architecture for globally distributed deployment of applications, providing tolerance to regional failures
Deployment strategy for enhanced customer response with localized routing of traffic
Architecture & design for load distribution and balancing, component level failure and recoverability
Automation for consistent deployment with required controls, ability to reconstruct the environment with automation should the need arise

Infosys delivers resilient cloud platform powered by AWS, adopting the AWS Well-Architected Framework and best practices.

TALK TO OUR EXPERTS

AWS services that are leveraged to build the architecture include:

AWS organizations encapsulate the boundaries of business processes and applications for better controls implementation
Local POP, AWS CloudFront, and global routing with Route 53 to ensure the shortest path to the region where the workloads are running
Multi-AZ deployment of application and components within the region with AWS global load balancers and application load balancers, to address components level failures and local data center failures
Multi-region deployment in AWS using geographically balanced infrastructure for better customer experience in each region, with ability to failure over across regions, to manage eventualities in a region
AWS control tower to automate the entire cloud platform and landing zone deployment, with necessary controls and governance
Strengthen incident management and recovery process and achieve best resilience and availability with thorough planning and periodic testing using AWS Resilience Hub

Challenges & Solutions

Businesses are apprehensive of cloud, especially from a customer experience and resiliency perspective hindering cloud adoption, which is essential for agility and growth.

Infosys Cobalt reference architecture for highly resiliency systems embeds the best practices as defined by AWS and experience from over 300+ clients. The solution works out of the box and guides through the implementation journey with prescriptive steps

Businesses and applications have varying level of availability and RTO/ RPO requirements, architecting the solution is time consuming and there is lot of trial and error

Infosys Cobalt engineering assets have deployment architecture patterns and automation kit for most of the common workloads in the enterprises across data stacks, application runtimes and more. The stacks are created with AWS IaaS services and AWS PaaS services for 3-tier architectures, event driven architectures, data ingestion and analytics applications, for multi-AZ and multi-region deployments.

Beyond architecture, design and deployment, there is need to continuous assess the environment’s resiliency and ability to recover.

Infosys adopts chaos engineering as part of platform engineering and operations to continuous evaluate the system capability to manage disturbances and failures and its recoverability to restore the services back with minimal disruptions. These are implemented using AWS fault injection simulator.
