In this paper I will be describing some of the features that the mainframe defined around performance, reliability and availability. In the last half of my paper I will then describe some of the cutting edge features of commodity server and cloud computing worlds that draw on paths first forged by the Mainframe. Mainframes have always been some of the beefiest computing platforms on the planet. For years they were the most powerful computing platform money could buy. Even with the advent of cloud computing and massive data centers filled with commodity hardware, mainframes are still unmatched in transactions per second. This type of processing is still the lifeblood of banks and many other businesses. To reach these levels of …show more content…
z/OS’s extensibility allows for no single points of failure, allowing 1, 2 or even 3 points to fail all without effecting the workload running on the mainframe. This level of fault tolerance also allows operators to perform rolling changes across a mainframe where they take down whatever pieces they need to perform maintenance or otherwise one at a time, all without the mainframe having a care in the world. Even with all these levels of redundancy however is not important most of the time in IBM’s world. Their mainframes are bulletproof. Mainframes have been known to run for years without going down and it is a point of pride for IBM. All of this parallelism means nothing however without a way to leverage it. Many applications and workloads can be programed to take advantage of the parallelism natively and deal with the inherent difficulties that it introduces. For workloads that haven’t or can’t, IBM provided a product to deal with it. The problems mainly revolve around data sharing and applications that cannot share data, they expect data to be directly connected. Intelligent Resource Director manages the provisioning of workloads that cannot take advantage of the parallelism offered by a Sysplex natively. It will move resources to where they are needed when they are needed for whatever workload is running. The next area that Mainframes
In centralized computer or minicomputer frameworks the assets like memory, stockpiling of information and system data transfer capacity ought to be managed carefully.
I believe most of the general populations are aware of how rapidly technology evolves. I will start by giving a little bit of background into my own computer system. I purchased my Desktop computer system in late October 2008. At the time I was set to begin a journey into the world of higher education and needed a computer that could keep up with me. As I did my research into what was on the market that would fit not only my budget, but the needs I believe I needed. I quickly found I was not interested in anything that was on the market in stores, simply because of
A quality paper will address requirements to compare and contrast both the server and workstation products from three different Linux vendors. A quality paper will have significant scope and depth of research to support statements. A quality paper will employ sound use of reasoning and logic to reinforce conclusions. Relevant illustration or examples are encouraged.
With time, the PC continued to evolve and newer models offered better speed, color screens, more memory and larger hard drives. Further technical evolution continued to deliver higher speeds, larger storage capacity both internal and external. In addition to the hardware progression, the PC world continued to see progress with operating system solutions and advanced software catering to both large and small businesses as well as the home owner.
Stability is a major advantage of Operating system- it very rarely crashes, loses data or freezes.
“Cloud computing may seem complicated, but it actually has way fewer issues than other infrastructures. Since the cloud runs on its own servers through a company whose only job is to make the cloud functional and bug-free, it’s usually a whole lot more reliable than your own, on-location server.” (Ismail, N, 2017)
Modern data centers and hardware that focus on energy efficiency, high availability, security and scalability to provide a physical infrastructure for our new IT vision to grow
Technology changes will significantly reshape IT companies like CA Technologies. CA has kept its mainframe and clients’ server business in the past 30 years. The company provides the latest mainframe innovations. But CA has to face a new challenge whether it continuous to keep major business in mainframe or make a thorough transformation from mainframe to cloud computing.
Reliable software and unreliable software is very important when it comes to computer systems. They both deals with the operation of the computer systems for a specified time. Without software, computers would just be hardware that has no specified purpose. There would never be any output or function for the computer systems because the software is what actually gives the system life. Software is not just used for the “everyday” computer that we sit down in from of in every day. It is used for multiple things such as pacemakers, airplanes, medical devices, and cellular devices.
You can imagine end users relying on the extended enterprise of those with the information, as a network of computers connected to the enterprise through a router or switch. All of the networked computers are going to have needs. Sometimes it requires a lot of processing power and sometimes it requires a little. Sometimes all of the networked computers will need something at once. To make the system work it is not enough to just build a system or infrastructure capable of the common tasks. There needs to be a supercomputer or nests of computers with the resources to tap into when needed. It has to be flexible to provide a lot of power to a few tasks, or some power to many tasks. The challenge is to build this infrastructure in the most efficient way possible.
Extra security and stability is needed. Resetting a mainframe should not happen as often as a personal computer. This is because a mainframe will affect hundreds to thousands of users.
Currently in today's complex computer systems environment there are more choices available than ever before. While
The twenty first century as the digital era offers a more accessible information and widely available anytime, hardware designers and software developers increasingly emphasize the way how the cloud computing shapes electronic hardware design and system dynamic control. The cloud can be described as an ecosystem, which contains applications and maintain computer?s resources. As the specific ecosystem it needs to meet particular requirement of an enterprise such as adaptability, quick response, extensibility and the security(1). This essay aims to discuss how cloud computing impacts on modern hardware and software applications. Firstly, this report examines the theory of cloud computing. Next, it discuss the impact of cloud computing on the infrastructure and how cloud computing is changing the way of software being built. Finally, it focuses on giving details about some potential risk that need to face and solutions which can help to create and bring a new revolution to hardware and software area in the future.
In 1978, Intel came out with the 8086 chip. This chip had 29,000 transistors, 20 address lines, and could “talk with up to 1MB of RAM ... designers never suspected anyone would ever need more than 1 MB of RAM” (PCMech, 2001, para. 4). Intel continued to produce its 8000 series chips, increasing the speed and the memory each time. In 1982, the 286 was the first processor to have protected mode, which was later used by Windows and other operating systems to allow programs to run separately but concurrently (PCMech, 2001, para. 8). In the late 1980s, Intel came out with the 386. The 386 was a huge step forward, as it had 275,000 transistors, came in a 33 MHz version, worked with 4 GB of RAM, and could support a virtual memory of 64 TB (PCMech, 2001, para. 9). In 2002, hyper-threading came out in the Pentium 4 HT, which meant that the CPU could be fooled into thinking it had two CPUs for each one that it actually had. Using hyper-threading along with additional cores has enhanced performance and speed because some cores are utilized for programs while others perform background jobs (Hoffman, 2014, paras. 6,7). Another way CPUs have been able to increase speed is by raising the number of cores per CPU socket, and utilizing an I/O Hub “called QuickPath Interconnect” (Santana, 2014, p. 565). The use of multiprocessing has been the key for the development of today’s CPUs.
The Multics operating system project undertaken at the Massachusetts Institute of Technology (MIT) in the 1960s was a novel and powerful approach that helped shape the subsequent course of computing technology. In particular, Multics served as the model for utility computing and the various kinds of on-demand software, platforms, and infrastructure services that exist today. Multics was the first instance of the cloud. Leaving networked computers inside, Multics also offered a novel approach to hierarchical file structures that served as a model for future security approaches.
