Virtualization offers cost-value, performance and security benefits by reducing hardware costs, providing virtualized applications that you can reconfigure easily and meeting all regulatory and compliance guidelines. You don't need to make a prohibitive capital investment, and easy expansion into cloud storage and new technologies means that you have virtually limitless scalability.
You can use one physical server to run multiple virtual servers, which drastically reduces equipment costs and operating expenses. Most servers today have more multitasking capabilities than most hosting applications use, and installing a multicore server allows you connect four, six or 12 cores to a single CPU. Choices of virtualization software allow you to run dozens of virtual servers with fewer CPU resources. If you use two or more servers for business, then switching to virtual servers helps you meet the challenges of cooling server rooms, containing costs and upgrading computing capacity as hosting demands increase.
Best Practices for Installing Virtual Servers
Eliminate as many servers as possible to enjoy maximum virtualization benefits, but make practical decisions based on your business circumstances. Don't risk breaching long-term maintenance contracts to virtualize your servers. You can take advantage of free tools from vendors that provide assessments of your hardware and software needs without committing to any single hardware or software solution. Other best practices when going virtual include the following ideas:
- Ensure that the software applications you use are compatible with virtual software.
- Some virtualization platforms may prove incompatible with older server hardware, so find out if your existing hardware can handle the job.
- Choose a hypervisor program that meets your specific business needs.
- Repurpose or sell redundant servers and hardware to generate greater cost savings.
- Arrange thorough training for maintenance staff so that they can operate efficiently in a virtual environment.
- More cores in servers provide better performance than higher speeds, so choose a 12-core server over a faster, four-core or six-core model.
- Regardless of server, more RAM always proves beneficial, so get adequate RAM for your computing needs.
Virtual servers reduce maintenance and cooling risks and costs, help you reclaim rack space and allow you to deploy new virtual servers rapidly. Key benefits include the following windfalls for your business:
Save Resources and Lower Costs - Reducing the number of servers saves energy, reduces maintenance expenses and streamlines server-room design. Servers generate enormous heat, and keeping them cool causes security risks and the need for expensive cooling equipment and monitoring. Using virtual servers reduces your carbon footprint, a key consideration for many people.
- Create Backups Easily - Physical servers generate risks of downtime and catastrophic failure, and recovery efforts depend on many factors including availability of a backup server, recovery of data and redeployment of server arrays. You can maintain multiple backup copies of virtual servers that can be brought online in minutes.
- Test New Technology Safely - Use virtual environments for testing new technology, applications and software independently of other company operations in case something goes horribly wrong. You can isolate testing from regular computing activity and deploy innovations only after they've been debugged.
- Avoiding Common Mistakes of Virtualization
Common mistakes of virtualization include the misconception that only free space is necessary. Storage is critical, but make informed decisions based on precise measurements and assessments of drive latency, growth patterns, traffic spikes and IOPs.
- Plan carefully to balance hardware components, manage capacity and automate processes to get the best ROI.
- Assess bandwidth requirements and security protocols for each type of data.
- Stagger computing load to prevent massive drains on any single server.
- Remember to plan for outages, redundancy and minimizing downtime.
- Get enough storage capacity to optimize writing and migrating large caches of data swiftly and securely.
Transitioning between traditional servers and virtual computing generates some practical problems, but these are easily solved by researching and testing virtual hardware and software, planning your server configuration carefully and determining whether your old servers are compatible with virtual technologies.
Virtual servers simplify IT administration, hosting, security and maintenance tasks. You can use virtual servers for your entire data center, or begin by virtualizing a simple file server. Use virtual environments to test and assess new technology without compromising core functions. You can simplify management of your data center by installing the right virtual server technology for your needs and save money on both hardware and operational costs.

The security devil is always in the details of the attack: the ones you've endured, the ones you prepare yourself to fend off, and the ones that, you fear, will catch you completely unaware and defenseless. The Internet of Things (IoT) is nothing if not an endless proliferation of details. It's the vision of a world in which continuous Internet connectivity and addressability is embedded into a growing range of human artifacts, into the natural world, and even into our smartphones, appliances, and physical persons. In the IoT vision, every new "thing" - sensor, actuator, data source, data con...

How do APIs and IoT relate? The answer is not as simple as merely adding an API on top of a dumb device, but rather about understanding the architectural patterns for implementing an IoT fabric. There are typically two or three trends: Exposing the device to a management framework Exposing that management framework to a business centric logic Exposing that business layer and data to end users. This last trend is the IoT stack, which involves a new shift in the separation of what stuff happens, where data lives and where the interface lies. For instance, it's a mix of architectural styles ...

The Domain Name Service (DNS) is one of the most important components in networking infrastructure, enabling users and services to access applications by translating URLs (names) into IP addresses (numbers). Because every icon and URL and all embedded content on a website requires a DNS lookup loading complex sites necessitates hundreds of DNS queries. In addition, as more internet-enabled ‘Things' get connected, people will rely on DNS to name and find their fridges, toasters and toilets. According to a recent IDG Research Services Survey this rate of traffic will only grow. What's driving t...

Scott Jenson leads a project called The Physical Web within the Chrome team at Google. Project members are working to take the scalability and openness of the web and use it to talk to the exponentially exploding range of smart devices. Nearly every company today working on the IoT comes up with the same basic solution: use my server and you'll be fine. But if we really believe there will be trillions of these devices, that just can't scale. We need a system that is open a scalable and by using the URL as a basic building block, we open this up and get the same resilience that the web enjoys.

We are reaching the end of the beginning with WebRTC, and real systems using this technology have begun to appear. One challenge that faces every WebRTC deployment (in some form or another) is identity management. For example, if you have an existing service – possibly built on a variety of different PaaS/SaaS offerings – and you want to add real-time communications you are faced with a challenge relating to user management, authentication, authorization, and validation. Service providers will want to use their existing identities, but these will have credentials already that are (hopefully) i...
