This paper has described and motivated a cost model that allow a ready comparison of different cloud service providers when applied to an industrial scale computing workload. If this section we propose a set of formulae that allow service costs to be compared between different cloud providers. Furthermore, although all the cloud service providers do support RAID configurations, for simplicity only non-RAID systems are considered in this paper. 0000238305 00000 n 0000277014 00000 n 0000202241 00000 n Standard prices apply to both instances, although reserved instances attract a discount. 0000029498 00000 n 0000244821 00000 n Finally we conclude with a discussion of limitations and proposed future work.

Assuming a mean discount rate of $$D=26\%$$, then servers that are active for more than $$730(1-D)=540$$ hours per month are better reserved. 0000195192 00000 n 2 / 15 This IEEE Cloud Computing tutorial has been developed by Cloud Strategy Partners, LLC. Thomas said that infrastructure savings can be the most significant part of the business case in terms of cost savings.

However, disk size is highly right skewed (See Fig. 0000032447 00000 n Wireless Netw (2018). It is pointed out that in order to quantify the benefits of cloud computing, detailed financial analysis is needed. Nanlin Jin is partly funded by Innovate UK—Knowledge Transfer Partnerships ( Project ID: 10596). 0000232543 00000 n We propose a new costing model that systematically evaluates cloud services, 0000159259 00000 n 0000167202 00000 n 0000227382 00000 n However there is limited research that investigates the strengths and weaknesses of their cost models in relation to different types of usage requirements. 0000192743 00000 n 0000274886 00000 n 0000267850 00000 n 0000183162 00000 n 0000217861 00000 n The costs of hybrid cloud models differ from provider to provider. Next the specific details of size, usage, and capacity of one enterprise data centre are discussed. This covers 336 out of 506 systems in use in the data centre. Most common uses of public clouds are for application development and testing, … 0000149268 00000 n But the pricing model differs from one cloud platform to another. That's a huge amount of excess capacity that isn't being used and is being paid for by companies. These include the variable cost of populating the data centre with hardware, and finally the variable cost of operating and managing the servers in use [4]. 0000122685 00000 n However, Google adds an additional cost that depends on the operating system image loaded onto the server. 0000200558 00000 n Open Access This article is distributed under the terms of the Creative Commons Attribution 4.0 International License (http://creativecommons.org/licenses/by/4.0/), which permits unrestricted use, distribution, and reproduction in any medium, provided you give appropriate credit to the original author(s) and the source, provide a link to the Creative Commons license, and indicate if changes were made. 0000143790 00000 n This paper describes service portability for a private cloud deployment, including a detailed case study about Cloud Storage and bioinformatics services developed as part of the Cloud Computing Adoption Framework (CCAF). 0000191515 00000 n 0000000016 00000 n 0000212193 00000 n The criteria include costs and the SLA, and the strategies include local side and the CCS. The pricing vectors in (USD $per hour) for the server classes from Table 1 for AWS and Azure are then respectively: Assuming a mean discount rate of $$D=28\%$$, then servers that are active for more than $$730(1-D)=526$$ hours per month (see 4.1) will be run as reserved instances. 0000248481 00000 n 0000203924 00000 n 0000193204 00000 n 0000263701 00000 n 0000236187 00000 n 0000285340 00000 n Of this, mean usage is 43.1%.
