Legacy System Modernization: A Complete Guide

Rate this post

The IT sphere is developing very rapidly. If software assets are not updated in a timely manner, they can quickly become obsolete and, instead of being useful, even cause harm. To qualitatively update applications or CMRs, you need to contact a reliable legacy software modernization company. Not all development teams are involved in software modernization. Sometimes it’s easier to create a product from scratch than to delve into the details of a large group. But some teams, despite the complexity, take on such work. Moreover, specialists who are engaged in solving such a problem know several approaches that allow customers to save time and money.

The main problems faced by software owners

A decade or more ago, few data center designers could have anticipated that information technology would change so dramatically. The most important of them are the following:

• Virtualization. In an effort to reduce CAPEX and OPEX by consolidating underutilized hardware, companies are making extensive use of server virtualization, which allows a single physical server, called a host, to support multiple virtual machines, each with its own operating system and required applications.

• Blade servers. These plug-and-play compute modules are often used in conjunction with virtualization. Several of these modules share power supplies, fans, cabling, and storage resources. By concentrating significant computing power in a small space, server blades can significantly reduce the footprint of data centers.

• Cloud computing. In an effort to reduce overhead and improve productivity, enterprises are actively adopting cloud computing. For example, the analytical company IDC expects that in 2015 the cost of public cloud solutions with delivery of applications and infrastructure resources over the Internet will reach 72.9 billion dollars. Private cloud infrastructures that use the same underlying technologies as public clouds but sit behind the owner’s firewall are also rapidly gaining acceptance in corporate data centers.

• Increased power density. Virtualization, blade servers and cloud computing. All this leads to the placement of an increasing number of increasingly loaded devices with an increased level of heat generation in a shrinking volume of space. As a result, all three technologies are helping to dramatically increase power density in modern server racks. In fact, if a typical rack for traditional servers consumes 4 to 6 kW of electricity, then the rack where the server blade chassis are installed can consume up to 30 kW.

Benefits of modernization

Upgrading computer systems can improve the availability and power of systems. However, the less obvious benefits should not be overlooked. The flexibility and versatility of the system is increased. For example, a modernized data center is better suited to accommodate a wide range of emerging technologies, such as cloud computing, as well as future innovations.

Improved serviceability is critical to customer service. Quickly solving maintenance tasks without compromising resource availability is one of the most important quality requirements. In 2021, uninterrupted operation is no longer a luxury but a necessity. Greater scalability is also one of the main conditions for rapid business growth. This includes the widespread use of cloud computing, as it makes it possible to save on servers.
