Key Cloud Design Goal: Redundancy, High AvailabilitySunday, May 06, 2018
A key benefit of virtualising the infrastructure is to construct a platform which provides best-of-breed and reasonable, redundancy, availability and access; along with continuity and recovery. Most on-premise systems suffer from a lack of provisioning of these services, and moving to a cloud-virtualisation platform will certainly offer the opportunity to create a highly redundant and failure-proof system.
Key reasons why Agile for Cloud deployments may failTuesday, April 03, 2018
Agile is far superior to Waterfall or stage-gate methodologies. However, barriers in the organization, culture and a lack of understanding of what Agile truly means, amongst other important factors; may doom some projects using Agile to deploy into the Cloud.
Virtual Machine ManagementSunday, March 18, 2018
Managing VMs in the Cloud is usually manual, intrusive and time consuming. It would include patching and maintaining the existing VM estate; procuring and deployment new VMs, assessing costs; and workloads. A goal with many firms with large VM estates is proper VM management through automation. This includes VM approval workflow, and automated provisioning systems, change control and ensuring that the security model is implemented. The following are some key considerations in automating VM management.
VM CONFIGURATION MANAGEMENT – 5 key conceptsSunday, March 18, 2018
An automated VM-cloud management system populates the configuration management database, with the server and compute resource detail of the VMS; as part of an automated provisioning process. This is called the ‘CMDB’ or configuration management database. The CMDB may reside within the ITSM platform, or more commonly, within the Cloud accounts on a server. The CMDB should be backed up and the information sent to another cloud platform for Disaster Recovery.
Phases and Categories of TOGAF and building robust ArchitecturesMonday, February 26, 2018
Architectures are iterative creations. They are not sequential, waterfall processes. This obviously means that iterative methodologies such as Agile-Scrum are necessary for projects to succeed. This does not mean, a dearth of documentation or proper planning. Quite the opposite. It does mean however, a limitation to creating relevant and impactful documentation, in which IS supports the Business Strategies and Objectives. The goal is to build a functioning IS Architecture. Not produce endless and quite useless artefacts. An open-standards approach to building aligned IS systems, through an iterative methodology is TOGAF (The Open Group Architectural Framework).
