Cloud computing – Is this the way the IT industry is headed?

cloud computing vs dedicated servers

Will cloud computing solutions replace the dedicated server hosting? Well this question you might have seen on many websites and it is obvious because everyone is talking about it as more companies’ even start-ups are using or willing to use cloud solutions. So is this the way the IT industry is headed?

In my personal opinion – NO

Most of the authors’ opinions are actually based on Gartner’s predictions; a leading technology research company. If you read articles based on their research you will see a massive amount of companies are shifting from dedicated servers to cloud computing. But there are certain applications and use cases that will require dedicated hardware for a while, for example banking systems. read more

Cloud computing – sometimes yes, and sometimes no

Cloud-Computing

All studies and key informant interviews with countless suppliers and others demonstrated the phenomenon of cloud computing which is just out of the starting blocks, so sometimes hesitant, sometimes bewildering, but everyone agrees that it will profoundly change the way we use IT.

Ask ten people a definition of cloud computing and you will get ten different answers. Cloud computing is becoming a phenomenon in which many have not even passed the trend. In a recent European study by, it appeared that nearly 75% of companies are still not convinced of the usefulness of the cloud, while 17% see it is as a technology trend destined to a short life. A mere 11% believe it has an evolution in hosting which is durable. read more

Server Infrastructure Optimization– Strategy and Planning

Server Infrastructure Optimization

Practices to reduce IT operating costs: This blog post shows how a company can reduce costs of its IT operations and improve the efficiency of IT resources by optimizing its main infrastructure and adopting the best practices in the operations of servers. The practices described are effective to reduce operating costs and free up resources (human and financial) they offer and add value to the company and its customers.

Introduction

Even in the best of times, IT managers face multiple challenges; providing excellent services 24×7 with limited budget makes things a little bit difficult to manage. Studies by different analysts indicate that about 80% of the companies IT budget usually devoted to the operations and maintenance. This leaves only 20% for IT innovation which is yet one factor increasing the values of the companies. In these uncertain economic times, with tight budgets, this ratio may change in favor of the operations and maintenance, which reduces the share for the improvement of services for the companies. read more

Cloud Computing Integration with Existing Infrastructure

Cloud-Computing

Bridges with SI companies (systems Integrator) can be established through cloud computing. Various systems allow interconnecting with very secure applications that are already installed in the SI companies with applications hosted on cloud computing platforms.

This interconnection between the client and the solution addresses the following aspects:

Integrated Authentication of users: users must authenticate the same way they are used to with application while accessing applications hosted on cloud platforms. For this, SSO (single sign-On) solutions and identify services can be implemented within the company or through SAAS solutions. read more
