Cloud Data Center Creation




The first step in creating a cloud data center is to identify the needs and scope of the project. This involves defining the business objectives, technical requirements, operational constraints, financial implications, and strategic options of the project. The following questions can help you to clarify your needs and scope:



  • What are the business drivers and goals of creating a cloud data center? For example, do you want to reduce costs, improve performance, enhance security, increase agility, or foster innovation?



  • What are the technical requirements and specifications of creating a cloud data center? For example, what are the expected workload types, volumes, patterns, and growth rates? What are the desired service levels, such as availability, reliability, scalability, latency, throughput, and quality of service?



  • What are the operational constraints and challenges of creating a cloud data center? For example, what are the regulatory compliance requirements? What are the environmental impact considerations? What are the human resource limitations?



  • What are the financial implications and trade-offs of creating a cloud data center? For example, what is your budget? What is your expected return on investment? What is your preferred payback period? What are the risks involved?



  • What are the strategic options and alternatives of creating a cloud data center? For example, do you want to build your own private cloud data center or use a public cloud service provider or both (hybrid cloud)? Do you want to use an existing site or build a new one? Do you want to use standard or customized components?



Once you have identified your needs and scope, you can proceed to choose the best location and site for your cloud data center. The location and site of your cloud data center can have a significant impact on its performance, reliability, efficiency, security, and cost. The following factors can help you to select the optimal location and site:

You also need to consider the cooling redundancy options, such as backup chillers, fans, and pumps. You may also want to leverage natural cooling sources, such as free air cooling or water cooling , to reduce your cooling costs and energy consumption.



  • Network availability and cost: You need to ensure that your cloud data center has access to high-speed and low-latency network connections. You also need to consider the network redundancy options, such as multiple carriers, routers, switches, and firewalls. You may also want to use network optimization techniques, such as caching, compression, load balancing, and content delivery networks (CDNs), to improve your network performance and efficiency.



  • Market demand and competition: You need to ensure that your cloud data center can meet the current and future demand of your customers. You also need to consider the competitive landscape of your target market. You may want to choose a location and site that is close to your customers, partners, suppliers, or regulators, to reduce the network latency and improve the customer satisfaction. You may also want to choose a location and site that has a favorable tax regime, incentives, or subsidies, to lower your operational costs and increase your profitability.



  • Environmental conditions and risks: You need to ensure that your cloud data center can withstand the natural and man-made disasters that may affect your location and site. You also need to consider the environmental protection measures and regulations that apply to your location and site. You may want to choose a location and site that has a mild climate, low humidity, stable geology, and low risk of floods, earthquakes, hurricanes, fires, or terrorist attacks. You may also want to implement disaster recovery and business continuity plans, such as backup data centers, data replication, emergency power supplies, and evacuation procedures.



After you have chosen the best location and site for your cloud data center, you can proceed to select the optimal cloud service provider and service level agreement. A cloud service provider (CSP) is a company that offers cloud services to customers over the internet. A service level agreement (SLA) is a contract that defines the terms and conditions of the cloud service delivery, such as availability, performance, security, support, pricing, and penalties.


Selecting the optimal cloud service provider and service level agreement can have a significant impact on the quality, cost, and risk of your cloud data center. The following criteria can help you to evaluate and compare different cloud service providers and service level agreements:



  • Service offerings: You need to ensure that the cloud service provider offers the type of cloud service that you need, such as infrastructure as a service (IaaS), platform as a service (PaaS), or software as a service (SaaS). You also need to ensure that the cloud service provider offers the features and functionalities that you need, such as compute, storage, network, database, analytics, security, or management.



  • Service levels: You need to ensure that the cloud service provider meets or exceeds the service levels that you require, such as availability, reliability, scalability, latency, throughput, and quality of service. You also need to ensure that the cloud service provider provides clear and measurable service level objectives (SLOs) and service level indicators (SLIs) to monitor and report the service levels.



  • Service support: You need to ensure that the cloud service provider provides adequate and timely support for your cloud data center, such as technical support, customer service, account management, billing, and documentation. You also need to ensure that the cloud service provider provides various channels and methods for communication and escalation, such as phone, email, chat, ticketing system, or online portal.



  • Service pricing: You need to ensure that the cloud service provider offers competitive and transparent pricing for your cloud data center, such as pay-as-you-go, subscription, or reserved instances. You also need to ensure that the cloud service provider provides detailed and accurate pricing models and estimates to calculate and predict your cloud data center costs.



  • Service penalties: You need to ensure that the cloud service provider offers fair and reasonable penalties for any breach of the service level agreement, such as refunds, credits, or discounts. You also need to ensure that the cloud service provider provides clear and simple penalty clauses and procedures to claim and receive your compensation.



Once you have selected the optimal cloud service provider and service level agreement for your cloud data center, you can proceed to estimate the capital expenditure and operational expenditure of your cloud data center. Capital expenditure (CapEx) is the upfront cost of acquiring or building the physical and logical infrastructure of your cloud data center, such as land, buildings, servers, storage, network, software, and licenses. Operational expenditure (OpEx) is the ongoing cost of operating and maintaining the physical and logical infrastructure of your cloud data center, such as power, cooling, security, network, support, management, and taxes.


Estimating the capital expenditure and operational expenditure of your cloud data center can help you to plan and budget your cloud data center project. It can also help you to compare the cost of different cloud service models, such as public, private, and hybrid cloud. The following steps can help you to estimate the capital expenditure and operational expenditure of your cloud data center:



  • Identify the components and resources that you need for your cloud data center, such as servers, storage, network, software, power, cooling, security, support, management, etc.



  • Estimate the quantity and capacity of each component and resource that you need for your cloud data center, such as number of servers, amount of storage, bandwidth of network, licenses of software, kilowatt-hours of power, tons of cooling, hours of support, etc.



  • Estimate the unit cost of each component and resource that you need for your cloud data center, such as cost per server, cost per gigabyte of storage, cost per megabit per second of network, cost per license of software, cost per kilowatt-hour of power, cost per ton of cooling, cost per hour of support, etc.



  • Multiply the quantity and capacity by the unit cost of each component and resource to get the total cost of each component and resource for your cloud data center.



  • Add up the total costs of all the components and resources that belong to the capital expenditure category to get the total capital expenditure of your cloud data center.



  • Add up the total costs of all the components and resources that belong to the operational expenditure category to get the total operational expenditure of your cloud data center.



Alternatively, you can use online tools and calculators to estimate the capital expenditure and operational expenditure of your cloud data center, such as AWS Total Cost of Ownership (TCO) Calculator , Azure TCO Calculator , or Google Cloud Platform Pricing Calculator .
