Key Modernization Strategies for IBM Power and IBM i

The IBM Redbook outlines several key modernization strategies for IBM Power Systems and IBM i environments, each tailored to specific business needs and technical requirements. These strategies can be broadly categorized into the following areas:

1. Application Modernization

Application modernization is a critical aspect of any modernization initiative. Many IBM i applications have been in production for decades, and while they continue to provide value, they may not be optimized for modern user interfaces, mobile access, or cloud deployment. Application modernization involves transforming these applications to take advantage of new technologies and architectures. This can range from re-facing existing applications with modern web interfaces to rewriting them using modern programming languages and frameworks.

One common approach to application modernization is the use of low-code/no-code platforms. These platforms enable developers to rapidly build and deploy new applications or modernize existing ones with minimal coding. They offer a visual development environment, pre-built components, and drag-and-drop interfaces, making it easier and faster to create modern applications. This approach can be particularly beneficial for organizations with limited development resources or tight deadlines.

Another important aspect of application modernization is the adoption of microservices. Microservices are small, independent, and loosely coupled services that can be developed, deployed, and scaled independently. This approach allows organizations to break down monolithic applications into smaller, more manageable components, making it easier to update and maintain them. Microservices also enable organizations to leverage different technologies and programming languages for different parts of the application, providing greater flexibility and agility.

The IBM Redbook provides detailed guidance on various application modernization techniques, including code refactoring, database modernization, and user interface modernization. It also highlights the importance of adopting a phased approach to application modernization, starting with smaller, less critical applications and gradually moving to more complex ones.

2. Infrastructure Modernization

Infrastructure modernization focuses on upgrading the underlying hardware and software infrastructure that supports IBM Power Systems and IBM i environments. This can involve upgrading to the latest generation of IBM Power hardware, migrating to a virtualized environment, or adopting cloud-based infrastructure. Infrastructure modernization is essential for improving performance, scalability, and resilience.

One key aspect of infrastructure modernization is virtualization. Virtualization allows organizations to consolidate multiple workloads onto a single physical server, reducing hardware costs and improving resource utilization. IBM PowerVM is a powerful virtualization technology that is specifically designed for IBM Power Systems. It provides advanced features such as workload partitioning, dynamic resource allocation, and live partition mobility, enabling organizations to optimize their infrastructure and improve availability.

Another important trend in infrastructure modernization is the adoption of cloud computing. Cloud computing offers a flexible and scalable infrastructure that can be provisioned on demand. Organizations can choose to deploy their IBM Power and IBM i workloads in a public cloud, a private cloud, or a hybrid cloud environment. Cloud computing can provide significant cost savings, improved agility, and access to a wide range of cloud services.

The IBM Redbook discusses various infrastructure modernization options, including on-premises upgrades, cloud migration, and hybrid cloud deployments. It also provides guidance on selecting the right infrastructure modernization strategy based on specific business requirements and technical constraints.

3. Data Modernization

Data modernization involves transforming the way organizations manage and use their data. Many IBM i environments rely on traditional relational databases, such as IBM Db2 for i. While these databases are highly reliable and performant, they may not be optimized for modern data analytics and business intelligence (BI) workloads. Data modernization involves adopting new data technologies and techniques to unlock the full potential of an organization's data.

One key aspect of data modernization is the adoption of data warehousing and business intelligence (BI) tools. Data warehouses are centralized repositories that store data from multiple sources, making it easier to analyze and report on. BI tools provide a range of capabilities for data visualization, data mining, and predictive analytics. By leveraging data warehousing and BI tools, organizations can gain valuable insights from their data and make better-informed decisions.

Another important trend in data modernization is the adoption of data lakes. Data lakes are centralized repositories that store data in its native format, without the need for transformation or schema definition. This allows organizations to store a wide variety of data, including structured, semi-structured, and unstructured data. Data lakes can be used for a variety of purposes, including data exploration, data discovery, and advanced analytics.

The IBM Redbook provides guidance on various data modernization techniques, including data warehousing, data lakes, and data integration. It also highlights the importance of data governance and data quality in data modernization initiatives.
