There could be multiple objectives for an organization to consider a move to the cloud for eg. Agility, Cost Savings, Flexibility, Continuous Iteration, and Innovation, Platform Breadth, or others. Similarly, all the workloads of an organization may not be suitable and compliant for cloud migration. To help you answer and make relevant and effective choices, it is important for you to do a Cloud Readiness Assessment.
Our Cloud Readiness Assessment approach includes interactive consultations with stakeholders to determine business practices, goals, and opportunities to arrive at a plan categorizing Applications to Re-host/Re-platform/Re-factor for Cloud.
A thorough analysis of existing IT assets is completed using the right assessment tools covering IT Infrastructure, Security posture & Risk assessment, DC environment, TCO Analysis, etc. Some non-technical aspects should also factor into your decisions about which applications should stay on-premises: licensing, support, and regulatory.
As a Cloud Service Integrator, one of the key responsibilities we provide is a highly resilient infrastructure for our customers. The ability to maintain high availability and fault tolerance is critical to ensure uninterrupted service and customer satisfaction. Following points explains the services and approach we use to build the resilient infrastructure in AWS Cloud
AWS offers multiple Availability Zones (AZs) within each region, which are physically separate data centers. By distributing your resources across multiple AZs, you can protect your applications and services from the failure of a single AZ. Design architecture to utilize load balancers, auto scaling groups, and database replication across different AZs, ensuring redundancy and continuous availability.
Auto Scaling is a powerful feature in AWS that automatically adjusts the capacity of resources based on demand. By setting up auto scaling groups, the resources are dynamically added or removed in response to changes in workload automatically. This ensures that the application can handle sudden spikes in traffic and also reduces costs during periods of low demand.
Elastic Load Balancing (ELB) distributes incoming traffic across multiple instances to enhance fault tolerance and availability. By leveraging ELB, the traffic is routed to healthy instances and seamlessly replace unhealthy instances.
To achieve high availability and disaster recovery, it is recommended to deploy infrastructure across multiple AWS regions. By replicating resources and data across different regions, we can ensure business continuity even in the event of a regional outage. Services like AWS Global Accelerator and Route 53 help route traffic to the nearest available region, minimizing latency and providing a seamless experience for your end customers.
Database failures can severely impact the availability of connected applications. AWS offers various options for database replication, such as Amazon RDS Multi-AZ deployments and Amazon Aurora Global Database. These replication mechanisms ensure that data is continuously synchronized across multiple AZs or regions, providing fault tolerance and minimizing downtime.
AWS provides a wide range of managed services that can enhance the resilience of the infrastructure. Services like Amazon RDS, Amazon S3, and Amazon DynamoDB offer built-in redundancy, automated backups, and high durability. By leveraging these managed AWS services, we can build resilient applications easily.
Proactive monitoring is crucial for identifying and addressing issues before they impact business. AWS CloudWatch, along with its various integrations, allows to collect and analyze metrics, set up alarms, and trigger automated remediation actions. By leveraging services like AWS Lambda, we can automate tasks such as instance recovery, database failover, and resource scaling, further enhancing fault tolerance and reducing downtime.
Organizations which have taken the Cloud CoE approach towards large scale migration have been far more successful than organizations who did not.
Large enterprises at the onset of their transformation journey often begin to unearth existing pockets of transformation that have escaped notice. What’s also important and which has led the existing pockets go unnoticed is that these good practices haven’t spread from these isolated corners of the enterprise and transformed the rest of the organization.
We think the answer is that transforming the whole of the enterprise requires…well, a large transformation. The enterprise must find a way to make its deep changes scale broadly until they reach critical mass. Cloud adoption represents a major IT transformation, a shift in culture and a new way of financing your infrastructure. It presents new cost and security challenges, requiring governance and control across the organization. It also needs a proactive team to take ownership and direction of the migration process. A Cloud Center of Excellence (CCoE) has rapidly become an indispensable method of performing just that role.
Cloud Center of Excellence (CCoE) addresses this core problem for enterprises in a way that your organization can gain leverage across the enterprise & drive the wave of change that can truly transform your organization. A Cloud CoE will also create a structured way to the cloud, helping your organization avoid the pitfalls and realize the full potential of cloud adoption. Our goal while helping you build your Center of Excellence team is to take a large, widespread, deep-rooted organizational problem and solve it in a smaller scope with an open-minded approach and then leverage the small wins to scale it across the organization.
