2. Info-Tech Research Group2 Today’s application portfolio can be expensive to maintain in light of increasing pressure to reduce costs. A poorly executed consolidation rollout can result in significant opportunity costs and crippled applications. Introduction Have many applications that use the same type of back-end and mid-tier components. Can no longer sustain the resource overhead of maintaining the existing application portfolio. Need a consolidation roadmap that is based on a cloud solution. Require an ROI-based business case to be built for Platform-as-a-Service (PaaS) recommendation. Determine suitability of PaaS for the current application portfolio. Determine the most appropriate PaaS adoption strategy based on opportunity/service mapping. Determine impact on your people, process, and technology stack for each opportunity. Create a prioritized list of services for rollout based on reusability. Communicate with stakeholders. This Research Is Designed for App Dev Managers who: This Research Will Help You:

3. Info-Tech Research Group3 Executive Summary App Dev Managers are under increasing pressure to perform more with less. This includes maintenance of legacy applications, undertaking new projects, and initiating new phases of existing projects. PaaS offers the ability to consolidate architecture components in the form of reusable services in a cloud infrastructure. Migrating to PaaS requires both a deep and broad understanding of your application portfolio. You must know all the architectural components in order to determine reusability. At the same time, you must also know how components are integrated. Start any PaaS migration with an assessment of applications that are important to the business. This provides the basis for maximum impact in a pilot phase. Implementing PaaS can have a significant effect on your application portfolio. The consolidation effort will reduce the architectural footprint, but any per transaction cost with a PaaS vendor can quickly offset any gains. Migrating to PaaS can also impact your technical team. If many of the commonly used services are migrated to a third-party cloud vendor, internal resources will need to be reallocated. It may also be necessary to train development teams on how to develop in a PaaS environment.

5. Info-Tech Research Group5 Today’s app development is under increasing pressure to reduce costs and increase scalability and accessibility Understand why development organizations are feeling the pain. The platform is the problem! App departments are frustrated! App development and maintenance departments are being pressed by CIOs to look for ways to reduce development and maintenance costs without deteriorating the overall app quality and throughput. The business is constantly pushing IT to improve app accessibility and increase service offerings. Given limited resources and a tight budget, developers are struggling to meet these demands. A poorly implemented or fragmented platform can increase the complexity of the IT architecture, which often leads to malfunctioning applications and high operation and maintenance costs. Traditional platforms tend to have limited scale and provision of new infrastructure is not possible. This limits the opportunity for reusability, driving up time-to-market and maintenance costs. The underlying infrastructure for on-premise platforms restricts the capacity and performance of a platform. This is a cloud PaaS value proposition – understand the relationship of specific infrastructure entities to platform services to fully discover opportunities for reusability and elasticity. [Using PaaS]… JPMorgan Chase achieved an estimated 700 percent increase in developer productivity, a 50 day reduction in time-to-market for new apps, a 30 percent increase in infrastructure utilization and a subsequent 45 percent reduction in associated costs. -- Deutscher M., “PaaS Boosts Developer Productivity, Infrastructure Utilization at Chase Bank,” March 2013

6. Info-Tech Research Group6 What is the industry saying? “80% of what you build will run better on PaaS – maybe even 95%.” -- Sacha Labourney, CloudBees “Enterprises that are moving some applications to the cloud are hoping to gain ‘greater resiliency and interoperability with different environments’ even if the applications weren’t originally designed for the cloud.” -- Paul Burns, Neovise LLC “You don’t need to put everything there, but you want to put 100% of your development on PaaS.” -- Labourney, CEO CloudBees “If I have that budget to spend on resources, I should be spending that budget and that time on developers who are going to be innovative.” -- Matt Fischer, Early PaaS Adopter “Managing cloud integration consumes roughly 10-12% of business’ PaaS budgets.” -- GetCloudServices, 2012 “Developers deem development environments (24%), test environments (14%), and migration among PaaS providers (13%) as the most important within various PaaS attributes.” -- “What are Developers’ Preferences on Platform as a Service? An Empirical Investigation,” Giessmann et al., 2013 “It’s clear PaaS is where the market is going.” -- Microsoft, Windows Azure Team

7. Info-Tech Research Group7 The cloud stack maps to an application stack. It is composed of SaaS, PaaS, and IaaS which are essentially the application, platform, and infrastructure layers in a cloud environment. Basic principles and practices still apply to the cloud since traditional concepts still hold true. Leverage your existing dev process to minimize the costs and impact. PaaS will streamline the dev and maintenance process with a small learning curve, reusable services, and an elastic architecture. PaaS improves the throughput and quality of app development and maintenance SaaS PaaS IaaS Pivot well known principles to the cloud Leverage the unique benefits of PaaS Reusable Services – PaaS contains a pool of modularized services which developers can leverage through APIs or other integration techniques. This reduces the amount of duplicate custom coding and integration. Supported by IaaS – Since PaaS is a service that abstracts IaaS, infrastructure is no longer a primary concern for you. In PaaS, the vendor’s infrastructure is made for elasticity and can easily scale up or down based on the needs of your application platform.

8. Info-Tech Research Group8 Rolling out PaaS follows a similar roadmap as classic platform migration View PaaS like any other platform: services are mapped to applications through a defined architecture that needs to satisfy stakeholder requirements. BusinessTechnical Stakeholder Requirements Applications Architecture Platform Services Applications are built from use cases which are defined by business requirements and they are structured based on a particular architecture. Integration points should be clearly defined to accommodate any app and architecture changes. The arrangement and composition of entities in an architecture are based on requirements. An application’s mapping to platform services is, in turn, defined by the architecture. Stakeholders expect a high level of accessibility, performance, and availability from their applications. Ensure that any changes to the platform do not result in deteriorating app quality and throughput. Implementing new services will disrupt the architecture in some way. Conducting an impact analysis of these services helps gauge the level of required change. © Info-Tech Research Group Platform Migration Impact Model
