Mainframes are still a critical part of the IT infrastructure for many large organizations. They are used to run mission-critical applications, such as those for financial transactions, customer service, and inventory management.
As a result, the decision of whether to outsource or manage mainframe services is an important one. There are pros and cons to both approaches, and the best option for a particular organization will depend on its specific needs and requirements.
Understanding Outsourcing and Managed Services
⇒ Outsourcing is the process of contracting with an external provider to perform a specific task or service. In the case of mainframe services, this could involve the entire mainframe infrastructure, or just specific tasks such as operations, maintenance, or security
⇒ Managed services is a more comprehensive approach to outsourcing. A managed services provider (MSP) takes responsibility for the overall management of the mainframe infrastructure, including operations, maintenance, security, and upgrades.
The main difference between outsourcing and managed services is the level of involvement of the organization. With outsourcing, the organization retains responsibility for the overall management of the mainframe infrastructure, and the MSP is simply a contractor. With managed services, the MSP takes on a more active role in managing the infrastructure, and the organization can focus on its core business activities.
Mainframe technology is here to stay, but the conversation around mainframes must evolve. We see a threefold answer through empowering mainframe teams by in-place modernization, a managed service model and bringing up new generation of mainframers.
The Mechanics of Outsourcing
Outsourcing usually involves transferring the complete mainframe infrastructure, including hardware, software, data, and personnel, to the provider. This provider then assumes responsibility for the entire management spectrum, from operations to upgrades. While outsourcing can be cost-efficient, benefiting from economies of scale and mainframe specialization, it might also curtail control over the infrastructure, potentially reducing flexibility and visibility.
Operational Focus of Outsourcing Providers
Outsourcing providers predominantly emphasize operations. Their expertise ensures smooth mainframe infrastructure management. However, their focus might not extend to generating new business value, concentrating more on fulfilling the organization’s existing needs.
The Comprehensive Nature of Managed Services
Managed services promise a broader spectrum of mainframe management. Beyond operational facets, they aid organizations in bolstering their IT prowess. MSPs identify and rectify improvement areas, leveraging their resources and expertise.
Security and Compliance in Managed Services
Managed services providers are typically very focused on security and compliance. They have the expertise and resources to ensure that the mainframe infrastructure is secure and compliant with all applicable regulations. This can be a major advantage for organizations that are concerned about security and compliance.
Disaster Recovery and Business Continuity
Managed services providers can also help organizations to improve their disaster recovery and business continuity capabilities. They can help organizations to develop and implement disaster recovery plans, and they can provide the resources and expertise to recover from a disaster.
