Your Path to Improved Business Scalability
Your Path to Improve Business applications performance relies significantly on databases. Digitalstates can help you migrate, optimize, and modernize your legacy databases on the AWS cloud, enabling better agility, continuity, and operational efficiency.
Database Assessment
Migrating complex Oracle workloads to AWS can be a complex and time-consuming process, but with proper planning and execution, organizations can successfully migrate their Oracle workloads to the cloud and reap the benefits of cloud computing. Digitalstates provides a comprehensive set of services and tools that allow businesses to migrate their Oracle databases to the cloud with ease. Our assessment phase involves understanding your system environment, key dependencies, integrations, and business requirements, and preparing the business case and ROI analysis.
Business Assessment
Involves determining the business objectives, downtime requirements during migration, service availability requirements, interruption impact, and total cost of ownership (TCO) in the cloud. right migration methodology, right deployment methodology, right team structure, and skillset. automation planning, timelines, and the risks involved.
Technical Assessment
Involves discovery of current infrastructure, business applications, and database dependencies, bare-metal and virtual servers, types and versions of hardware, database, and OS, server utilization and load profile, as-is architectures of the current deployments, current team structure, Oracle skill set, cloud architecture and automation knowledge of the team, documented process flows and runbooks.
Challenges Assessment
Understanding complicated real-time situations and challenges is the key to uninterrupted cloud migration. It includes shortening business downtime, minimizing risk, moving to a different OS or environment, support issues, versions and functionality mismatches, application upgrades, lack of knowledge in system replacement projects, limited time to examine things, and identifying the best migration method.
Database Migration
Migrating on-prem databases from the data center to the public cloud without causing any business disruption is tricky. Expensive application failures can be avoided through a team of experts and best practices. Some approaches to migration are only valid if certain properties of the on-premises and destination databases are compatible. Even if more than one migration strategy is technically possible, it may still come down to non-technical considerations. Digitastates has extensive experience and best practices to transfer Oracle database and eBusiness Suite workloads to the AWS cloud.
Migration Preparation
Involves determining the right method to migrate Oracle to AWS and factors including the version, character set, and platform endian format of the source and target databases, Amazon EC2. RDS, VMware on cloud, data pump, conventional RMAN backup and recovery, database upgrade wizard. transportable tablespaces, full transportable export/import, data guard, incremental backups, Oracle GoldenGate, Shareplex, Streams, and AWS DMS.
Migration Strategy
When deciding on a migration strategy, it’s important to think about the following features and factors including source and target database versions, source platform and OS, source database character set, volume of data, including indexes, methods available for data transportation, database features and data types used, storage for data staging, the acceptable length of a system outage, and network bandwidth.
Migration Tools
When it comes to migrating Oracle workloads, AWS delivers a wealth of resources and guidelines such as the Migration Acceleration Program (MAP) and Database Migration Service (DMS), which helps in automating the migration process. In addition, AWS provides a wide range of services like Amazon Relational Database Service (RDS), which can be used to host Oracle databases in the cloud.
Database Optimization
Modernizing and optimizing the database during and post cloud migration for a more scalable, secure, available, and cost-efficient architecture and application delivery is important. Infrastructure, configuration, monitoring, and data migration automation plays a critical role in complex and large-scale Oracle migrations. Digitalstates recommends creating environments using automation (Cloud Formation Templates, Terraform, Ansible, Scripting) and offers strategies to sustain your business growth.
On-going Adjustments
It is important to perform continuous monitoring and optimization of server performance and data migration status. The runbooks are also essential from validating server build to performing cutover tasks.
Benchmarking Results
By understanding the architecture of your Oracle databases and applications, securing sensitive data, implementing proper networking and data management practices, and ensuring optimal performance, organizations can ensure a successful migration to AWS.
Bridging the Gaps
There are many important factors to consider when migrating Oracle workloads to AWS such as designing architecture for failure using high availability guidelines, isolating nodes based upon role, implementing horizontal scaling, building security in every layer along with data encryption and firewalls, designing an efficient and reliable backup strategy, ensuring high-speed connectivity between on-prem and cloud environments, and using the right IOPS options for each level.
