The mainframe support team has a requirement to re-acquire Performance and Capacity resources to keep pace with the demand. The Resource will be responsible for the day-to-day Performance and Capacity activities as well as provide planning, configuration and software currency activities for the Z16 and DR Mainframe which was installed this past spring. This Hardware Fee for Service request came about as a result of the end of the DR contract with Kyndryl and we have a business requirement to pivot and acquire our own hardware to prevent mission critical services from running without a disaster recovery plan. As an outcome of this DR business decision, we installed a 2nd Z16 mainframe. In addition, there are also modernization efforts to reduce software costs with some products running on the mainframe (Software Optimization). The resources will provide support for the mission critical services across all OPS clusters and ministries. While Cloud is the future of service delivery for midrange IT, there is still requirement to support and modernize the mainframe environments. There is a limited number of Mainframe platform skillsets available in this niche marketplace. We need to ensure to maintain availability and upgrade mainframe capacity to support software and program product support continuity (day to day operations). Currently ITOD does not have sufficient skills and headcount in house to support the ongoing work related to upgrading our Mainframe hardware platform and KTLO activities due to FTE attrition.
This Resource will act as a subject matter experts on a variety of Mainframe performance and capacity analysis and reporting activities such as:
Enabling and supporting the day to day operations of the Government of Ontario's Mainframe performance and capacity disciplines to maintain KTLO activities and project work relating to the planning, installation, maintenance, upgrades of software products in support for post GDC Mainframe migration activities as well as the most recent Mainframe acquisition for Disaster recovery at our CO-LO site.
We need to ensure Mainframe Performance and Capacity system support for continuity (day to day operations) and projects as listed in the operational plan. ITOD hosts an extensive amount of mission and business critical applications that reside within Mainframe platform services and continued support to our now internally supported Disaster Recovery (DR) plan and build out.
This resource will also support the Software Optimization efforts under the Datacenter Transformation project.
