Servers

Need a Remote Authentication Dial-In User Service (RADIUS) server for your authentication, authorization, and accounting (AAA) needs? You can spend thousands on RADIUS solutions, but there are also a number of low-cost alternatives. These solutions are especially useful for smaller organizations that may only be using it for a single purpose, such as to implement enterprise WiFi security with 802.1X authentication. Many, however, can also...

While advances in virtualization and containerization are reducing the number of physical machines a server needs, growing businesses will invariably need to deploy servers in a larger physical space. However, a purpose-built data center is out of reach for many budgets. That's why colocation data center providers offer a superior solution to traditional, on-premises server rooms.

What Is a Server? Servers are high-powered computers built to store, process, and manage network data, devices, and systems. Servers are the engines powering organizations by providing network devices and systems with adequate resources. For businesses, servers offer critical scalability, efficiency, and business continuity capabilities. Whether it's hosting a data-heavy website, setting up a shared drive for a department, or managing thousands of queries every minute,...

Server security tools used to be focused on safeguarding physical servers. Each box required login credentials, and administrative privileges were required to change anything. Software such as antivirus and malware protection were directly installed on each machine. These days, the physical server is just another endpoint — albeit an important one. There are many ways to protect server resources, including backup, antivirus, patching, intrusion detection,...

Server security services stop the worst from happening. Hackers who get into a single user's systems may find something worth stealing, but chances are there won't be much to gain. It's the servers — with their databases, confidential information, and complete enterprise user files — where bad guys cause the most havoc. Gain access to a server, and you can lock all enterprise systems and...

Containerization is the solution to the roadblocks posed by traditional virtualization. Since their inception, virtual machines (VMs) have enabled organizations to do more with less. A single physical device can contain several isolated, virtual environments through a hypervisor, and the benefits include reduced overhead, convenient mobility, and scalability. Sounds great – but there’s one problem. Virtual machines are heavy units. Because a significant appeal of virtualization...

The power of computers transformed the world in the last century. Today, they serve our critical infrastructure, business operations, and more. Though tempting to think of a universe of physical machines in office buildings and server farms, virtual machines (VMs) have actually been the cornerstone of enterprise computing in the new millennium. A VM gives administrators the power to manage hundreds of virtual computers from...

Blade servers and rack servers are the stock-in-trade of data centers, chosen for their versatility, security, and ability to configure and connect large amounts of computing power in small spaces. But while blade servers and rack servers accomplish the same goal of organizing your server base, they do it in very different ways. Which one of them you choose could have big impacts on...
