Cloud computing costs after another, the price advantage or will not be obvious

Once upon a time, the price is considered the first of several benefits of cloud computing, cloud products to provide users with easy and affordable resource supply, and the price is flexible, but in the real work load is deployed to the cloud, there are many in addition to the instance price Outside the cloud computing costs need to be considered. Beyond the basics of server instances, cloud computing costs often include storage, networking, load balancing, security, redundancy, subdivision, application services, and operating system licenses. And there are several cloud computing costs that will surely surprise you: resource conflicts, storage, bandwidth and redundancy. Server Instance Performance and Supply Costs As you have a annoying neighbor, other tenants in the cloud and you share the same hardware, which inevitably leads to resource conflicts, and this is a very common problem. "In a public cloud, you might be inclined to have more capacity, but because annoying neighbors consume more resources, the amount of host resources you expect to reduce, resulting in a slow response from a particular host, or having to frequently change hosts , "Said Jim O'Neill, CIO at HubSpot, a provider of hosted market software." We are more inclined to add extra investment to additional capacity simply to maintain performance at a known state. "However, sometimes super Capacity reservation is needed, and in the opposite direction is also easy to mismanage, said Jared Reimer, co-founder of Cascadeo, an IT consultancy. "If you do not continue to research and properly handle instance specifications, storage pools, memory usage, etc., the costs can become prohibitively expensive," Reimer said. "For example, we see companies using their own VMware Converter to virtualize Machine Image to Amazon Instance, Rebooting, Then Cost Continues, 'What?' The answer is that they turned these into large instances when there is no good reason to do so. "The new client assumed that the initial deployment needed to be done Cloud computing costs soar as potentially larger internal infrastructures move to the cloud, said Anthony Pagano, director of IT consulting firm StrataScape Technologies. "If the business is in a slow growth period, you can shrink," Pagano said. "If you start high and then shrink back, you can not be lower than initially set." If you set yourself too high a threshold , Need to be renegotiated, and the hidden costs are waiting for you. "Do not forget that data storage storage performance and contention is always a cloud problem, and although there are ways to improve it, it is not free, Sean Perry said, he is a professional human resources Robert Half CIO company. In particular, Amazon Web Services (AWS) has added functionality to its storage options so users can get Elastic Block Storage (EBS) optimized instances and specified IOPS / capacity. These costs "looked small at that time, but the cost increased with the increase in number of bytes and the number of bytes, the cost would be fierce," Perry said. For example, the company mimicked complex tests in May to determine how fast complex data was going to SharePoint running on AWS, using pre-allocated IOPS performance and EBS-optimized instances. "Suddenly we found the bill giving us the feeling of God," Perry recalled. The total cost of pre-allocated IOPS accounts for 50% of the total AWS costs, about 11,000 US dollars. While many people see cloud backup as a low-cost alternative to traditional backups, they can easily become storage-related cloud computing costs, especially for snapshot backups, which capture data from multiple points at a time of day. Cascadeo's Reimer said it's easy to make a snapshot backup and will forget about trimming the dataset. This means that this data continue to take up backup space. "Then I got a twenty thousand dollar deposit bill and I wanted to think 'what happened?'" Reimer said. "The answer is: you have ten thousand different backups and you need to clean it." Disaster recovery, monitoring and networking Bandwidth Considerations Disaster recovery server instance redundancy is often a neglected cost, according to an engineer in charge at an anonymous Fortune 100 company. Any new cloud deployment at this company requires at least 12 to 24 machines, leaving a proper redundancy and control in place. "We only run the smallest amount, because there is constant replication costs to keep the data, to be monitored and controlled, and to optimize," he said. In addition, there is network bandwidth. While vendors such as Amazon and Rackspace had very clear network bandwidth, they had to consider server and storage cost related costs. "If you are highly dependent on your previous data center location, you may not be suitable, and you understand that if you are always going to back-end calls," said Matt Lipinski, architect at Reed Elsevier Technology Services. Cascadeo's Reimer said bandwidth costs may not be immediate in a given environment. With AWS Direct Connect, for example, customers have their own private circuits that connect directly to the Amazon data center and Amazon still measures traffic. So, even if customers pay for telcos' fixed-capacity circuits, "you still have to pay twice," Reimer said. As of press time, Amazon did not make any comment.
