  Why the Mainframe Needs Modernized Protection and Connection

  By:

  Type: Video

  The mainframe lives in a connected, digital, hybrid IT World. It must meet a new generation of demands while continuing to extend enterprise-level security to an ever-changing world of business applications. Traditional host platforms, such as IBM Z, IBM i, HPE NonStop, or Unix, are well-suited to play a pivotal role in digital transformation. These vendors have rigorously innovated the platforms over the years to expose their functionalities to internal and external systems. Join a guest speaker from IDC for valuable insights for your protected and connected digital mainframe and hear from Micro Focus for simple technology steps you can adopt today to meet security, privacy, and mainframe access objectives.

  How server virtualisation is evolving to cloud native environments

  By: TechTarget ComputerWeekly.com

  Type: eGuide

  Server virtualisation has given businesses the ability to abstract applications and the operating system from the underlying hardware. For years organisations have used virtualisation to gain greater levels of utilisation from their hardware investments, where one big server is divided into multiple VMs (virtual machines), each of which can be configured to run a workload, comprising an operating system and a software environment.

  Businesses can deploy appliances, known as hyper-converged systems, that combine CPUs, storage and virtual server environment, all in one box. These tend to be horizontally scalable, enabling IT departments to grow their virtual server environment simply by adding another appliance. The management software in hyper-converged systems takes care of distributing workloads to maximise the greater level of computational power and storage available.

  Today, thanks to the advent of infrastructure as a service, organisations can choose to run their VMs locally, on premise, or in a public cloud using IaaS (infrastructure as a service) from any of the major cloud providers.

  Among the biggest problem areas in server virtualisation is the idea of VM sprawl. Since, they are not physical servers, VMs can easily be created. Often, however, they are not removed if they are no longer required. On-premise, this may not create such a big issue, since a dormant VM does not really consume resources like CPU, memory and storage. But if they are left to run indefinitely in the background, they will continue to consume valuable IT resources. In a cloud environment, businesses can incur huge fees if they fail to administer their virtual servers properly.

  While server virtualisation is a well-established method to reduce IT costs by consolidating on-premise servers and running appropriate workloads in the public cloud, a new IT architecture is now emerging. Rather than virtualise existing software environments, new applications are increasingly being developed to run natively in the cloud. This approach departs from the horizontally integrated software stack that applications have traditionally been built upon. Instead, the application code is divided into functional units known as microservices, each of which runs in a lightweight virtual environment known as a container. The code within the container, can be an internally developed microservice, or one from an external provider. A cloud native architecture uses containers to run a set of microservices in order to perform a required function programmatically.
