What is the Internet of Things?

You probably didn't notice anything different when you accessed the web on June 7th 2012, but a new and improved internet had replaced the old one virtually overnight. The new version, referred to as Internet Protocol Version 6 (IPv6), had been in the works for years and will shepard in the next generation of internet usage where the various and sundry items of everyday life are connected. This is what is being referred by the moniker “The Internet of Things” as potentially every “thing” can be connected over the web.

To get to the point where the next generation of “things” could be connected, the old internet with a paltry 4.3 billion URLs available had to be replaced with the current version, which has trillions more addresses available, according to Vint Cerf, one of the original inventors of the internet. The explosion in available addresses paves the way for next paradigm of internet connectivity where everything from cattle on the north 40 to the refrigerator in the kitchen can be accessed.

The key to this new paradigm is the evolution of sensor technology, which has dramatically reduced prices while increasing their functionality to enable the assessment of local environments, provision of location data, and the ability to transmit information over the internet via wireless technology. The number of “things” that will be connected to the internet is estimated to reach 50 billion by the year 2020, which could spur the development of new industries, products and services dedicated to the simplification of connecting items in homes and business. In other words, the Internet of Things, despite its current low profile could be one of the biggest things to hit the web in a long time.

Virtual Storage - By Anthony Ricigliano

Author Anthony Ricigliano - News and Articles by Anthony Ricigliano: While it’s true that information is king, he’s definitely a greedy ruler! As the business world continues to demand the storage of more and more data for longer periods of time, the need for increased amounts of disk space grows exponentially larger each year. To compound the issue, the low price of storage space means that many software developers no longer feel the need to make their products space efficient, and government regulations seem to increase legislative requirements for the retention of critical information each year. As the business units see the price tag on servers and disk space become more affordable, they can’t understand why adding just one more should be a problem. They fail to recognize that the cost of a growing computer room includes more than just the initial cost of the storage units.

The Shocking Cost of Maintaining Storage Units

Most non-IT workers would be shocked to find out that the cost of managing each storage unit can be as much as four to 10 times the original purchase price. In addition to putting a big dent in the IT budget, ever increasing storage units lead to server sprawl and a constantly declining operating efficiency. Increased maintenance can also be disruptive, expensive, and burdensome to the entire enterprise. To solve this problem, system engineers have been working on file virtualization methods to eliminate these issues. Their goal is to reduce storage and server inefficiencies while permitting infinite growth. Let’s take a look at exactly how they intend to accomplish this lofty goal.

Breaking the Tight Connection between Clients, Servers, and Storage

The old strategy of tightly coupling storage space with clients and servers is a big reason that adding a new storage unit becomes expensive to maintain. When machines from a variety of vendors are added to the network, they may not all integrate seamlessly creating individual islands of storage to manage. When applications are physically mapped to a specific server for storage, any changes, including additions, require modifications to this complex mapping algorithm. In some cases, adding a new device or moving a system to a storage unit with more space requires expensive and annoying downtime. This often leads to an under-utilization of the actual storage space, an expensive proposition, because system administrators over-allocate space to minimize the need to take an outage. To break free from this outdated methodology, file virtualization relies on the ability to remove this static mapping process to allow storage resources to freely move between applications as needed without restricting access to the data.

Adding a Layer of Intelligent Design to the Network

File virtualization adds a layer of intelligence to the network to decouple logical data access from the physical retrieval of the actual files. This separates the application and the client from the physical storage devices so that static mapping is no longer needed. With this change, the existing bank of servers can be maintained without disrupting the core system or the user’s access to valuable information. After implementing a file virtualization strategy, many IT shops find that they can consolidate storage units and increase their overall utilization. In this way, they may be able to simplify the system configuration by decommissioning older storage devices that are no longer needed or that they can go much longer than anticipated without adding additional disk space.

In today’s IT world, most shops are finding that using a file virtualization system is not only a “best practice," it’s a must-do to continue operating. IT shops with budgets that continued to rise each year just a short time ago are seeing their available funds shrink more and more each year. With increasing pressure to reduce costs or keep the flat, file virtualization is also a virtual requirement.

Virtualization for the Dynamic Enterprise

Anthony Ricigliano News - Business Advice by Anthony Ricigliano:

What does Server Virtualization Mean?

Server virtualization is the use of technology to separate software, including the operating system, from the hardware. This means that you can run several environments on the same physical server. In some installations, this could mean that several identical operating systems are run on the same machine. Other shops could decide to run a Windows platform, a Linux system, and an UNIX environment on a single server.

Advantages of Server Virtualization

In today’s demanding business environment, server virtualization offers many different advantages. Not only does virtualization allow servers and data to be more mobile than ever, it also provides a cost-effective way to balance flat or shrinking budgets. The following list details the major benefits:

• Consolidation – Most large servers run applications that only take up a small percentage of their processing power. Even busy software packages usually only have small peak times that utilize over 50% of their CPU capabilities. The rest of the time, the capacity is unused. By virtualizing the server so that additional systems can take advantage of under-utilized resources, IT shops can increase their return-on-investment (ROI). Although some companies have reported a consolidation ratio as high as 12:1, most shops can easily show a 3:1 to 4:1 rate.

• Decreased Footprint – By decreasing the number of physical servers, the size of the computer room can be reduced and utility costs should decrease.

• Lower Hardware Costs – The utilization of a higher percentage of existing hardware resources will reduce the total number of physical servers that are needed. This will save money on the upfront expense of purchasing hardware and the long-term cost of maintenance.

• Flexibility – Server virtualization allows an IT shop to be much more flexible. Instead of waiting for new hardware to arrive before implementing a new system, a new virtual server can be created on an existing machine. This also provides a more flexible method for migration and disaster recovery.

• Easier Testing and Development – Historically, IT installations have used separate physical servers for their development, acceptance testing, and production environments. With virtualization, it is an easy process to create either different or identical operating environments on the same server. This allows developers to compare performance on several different environments without impacting the stability of the production system.

Virtualization and Disaster Recovery

The growth in both international business and large-scale natural disasters has many organizations closely analyzing their disaster recovery plans and general hardware malfunction procedures. In either event, it is critical to be back up and running in a very short period of time. Most modern IT shops require consistent up-time 24-hours a day to maintain their core operations, or their business will be severely impacted. Both reliability and accessibility are greatly improved when server virtualization is used to its fullest potential.

By reducing the total number of servers needed to duplicate the production environment, it is much less expensive to create and test an off-site disaster recovery environment. Hardware, space, and backup expenses are dramatically reduced. It’s easy to see how setting up 30 or 40 pieces of hardware would be both easier and cheaper than configuring 100 items.

Along the same lines, a hardware malfunction will be less of an issue with server virtualization. While many more systems will run on the same piece of hardware, most shops find that they can easily duplicate physical servers for automatic rollover in the event of a hardware failure when they virtualize.

Major Virtualization Products

While there are always smaller players in any new technology, VMware and Microsoft Virtual Server are the biggest providers of server virtualization products.

• VMware offers the free VMware Server package or the more robust VMware ESX and ESXi products. Systems that are virtualized by VMware products are extremely portable and can be installed on virtually any new piece of hardware with a low incidence of complications. The system can be suspended on one machine, moved to another one, and immediately resume operations at the suspense point when restarted.

• Microsoft Virtual Server is a virtualization product that works best with the Windows operating systems, but can also run other systems like the popular Linux OS.
