Whitepaper Cloud Infrastructure: Start Small, Think Big_English

  1. 1. Every cloud concept can be developed within four weeks CLOUD INFRASTRUCTURE: START SMALL, THINK BIG whitepaper
  2. 2. The Infrastructure as a Service (IaaS) market is young and dynamic. Services are developing rapidly and standards have not been defined yet. Due to the lack of standards a vendor lock-in is a realistic, but undesirable scenario.This might be an argument to wait until the market has been more crystallized. By waiting, organizations leave opportunities unused to accelerate and make their IT services more flexible.Therefore, it is not unusual for IT departments to be seen as rigid and inflexible by their internal customers. “Because we use IaaS for our OTAP processes we can deliver new software every week instead of once every six weeks.” - Head of Infrastructure, Financial Organization Organizations that develop their own software often deal with rigidness and lack of flexibility caused by their infrastructure. As a result of methods like agile and scrum, software can be developed a lot faster than it can be delivered. Delivery has suddenly become the bottleneck. The solution to this problem is a software-defined infrastructure combined with a methodology of continuous delivery. In time you can convert your own datacenter to a software-defined datacenter (a private cloud), but it might take a few years to do so, while IaaS-providers offer such a ready-to-use infrastructure as we speak. Why not take advantage of this and gain experience right now? Business case for IaaS A business case for IaaS is easily made.This is not because the public cloud is by definition much cheaper, it depends mainly on the character of the workload: continuous or in peaks. In case of fluctuating workloads the financial business case for the public cloud is best to demonstrate. Not only the character of the workload but also the complexity of the pricing model is important.To make a proper cost estimate, expertise of existing infrastructure is necessary as well as knowledge of the range of cloud options. The business case is built on the degree of cost reduction and/or shortening the time-to-market for new software.The latter is by convenience of a software-defined datacenter that makes DevOps possible: technological and process If the effectivity of your cloud concept can not be proven within four weeks, it will not succeed within four months or four years.Therefore, always start off with a Proof of Concept when considering a migration to IaaS 2012 2013 2014 2015 2016 0 50 100 150 200 0 25 50 75 100 31 35 39 43 46 16 20 24 28 33 6 9 13 18 24 Billions of dollars % of ECC price in 2012 Cloud System Infrastructure Services (IaaS) Cloud Application Services (SaaS) Cloud Business Process Services (BPaaS) IAAS CAGR = 41,4% Source: Gartner, February 2013 Public Cloud Services Market Segment, 2012 - 2016
  3. 3. integration of development and operations. One of the core principles of DevOps is continuous delivery: small updates of software, multiple times a day. Since the updates are small, the impact of a mistake is limited and the risks in software delivery can be minimized. Moreover, all developers work in a uniform environment, which results in higher predictability. In short, IaaS results in an increased number of releases, while at the same time minimizing risks. Which software development team does not have that on their wish list? “Before we introduced IaaS for development, testing and acceptance environments we released new functionalities a couple of times a year.This led to peak periods for our helpdesk, because we received numerous questions from clients who, for example, were unable to find their ‘standard button’, because it was moved. After the introduction of continuous delivery changes do not have such a big impact anymore, leading to less and better diffused questions for our helpdesk Customer satisfaction has increased and our internal processes are more efficient.” Operation Manager Front Office System, Service Company Another business driver is the unlimited scalability of IaaS services. Which is useful when you do not know in advance how much your application is used.This can be the case when, for example, short term marketing campaigns are directed to a large public. “In our industry many websites and applications perish in their own success. Due to a large concourse in the peak period websites crash on the most important moments. We did not want to take that risk any longer during the publication of our annual reports. With the cloud solution our website had ten times more visitors in one day and the platform did not even budge. Moreover, since it was a short time operation, the pay-per-use model of IaaS made this a very cheap solution for us.” Corporate Online Manager, Multinational Not everything is suitable for IaaS Not every application is suitable to host in a cloud environment. Applications that are developed to scale vertically (increase capacity of the server) do not function within the current public IaaS environments, where the scalability is organized horizontally (by adding servers). Unfortunately most of the critical business applications, such as ERP, CRM and BI, are not yet scalable horizontally. Organizations with a lot of critical business applications and dedicated high-end servers are therefore hesitant to migrate from their datacenter to a cloud platform. Although understandable, doing nothing is leading to an organization that does not serve their business department to the optimum. “Nowadays when our marketing department thinks of a campaign–for example temporarily providing a barbeque when buying new garden
  4. 4. furniture because a weatherman forecasts barbeque weather for next week–we can adjust the capacity of our online shop within one day. We became a lot more flexible. IT is no longer our hindrance, but it has become a driver for our business growth.” Online Marketing Manager, Multi-Channel Retail Company When the private infrastructure has a limited scalability and is not automated sufficiently, a solution is found in diverting these modern web applications to IaaS services of cloud providers. Start small, think big: Proof of Concept Would you like to transform your infrastructure into a business enabler? When you identify the gain or compelling business event, then the next step is a Proof of Concept for testing your cloud concept in a short time frame.The small investment in a PoC is only a fraction of traditional IT project costs.The usual PoC project will take about four to six weeks.This small step will provide a solid ground and sufficient support within your organization, which you need for bigger further steps. Morgan Clark is a business technology consultancy company with extensive experience in next generation infrastructure projects. Next to supporting and defining your business case, we assist in executing your transition to the cloud. Our consultants, architects and program managers will support you during your thinking process, demonstrate in which cases IaaS will and will not work by using a PoC, and they lead you through the transition, among which the necessary reorganization of your infrastructure department and stakeholder management. Since 2010 Morgan Clark has performed over 60 successful projects for clients in industries as finance, telecom, media and service.These projects concerned transformation programs, next generation infrastructure, user mobility and data driven solutions. 37% Up-Front Investment 49% 51% 62% 69% 85% 0% 25% 50% 75% 100% Technology Immaturity Legacy Applications Lack of Business Support Lack of Internal Skills Lock-In Existing Partner Source: McKinsey, January 2014 Biggest hurdles to upgrading IT infrastructure
