New IT paradigms are created and find markets and proponents at a blistering pace \u2014 Cloud, Hyper-Converged, Software Defined, ____-as-a-Service, Flash Storage, and on and on. We are asked daily by our clients (representing companies of all sizes and a diverse set of industry verticals) to help them increase their IT\u2019s \u201cadaptability quotient\u201d so that these firms can continue to thrive.<\/p>\n
To respond to our clients thoughtfully, CMI<\/a> has developed the Adaptable Data Center<\/strong> reference model and perspective to assist in better understanding the issues and how many of the different pieces fit together.<\/p>\n There is no special magic to the model, but rather an approach to hopefully add some disciplined insights when making important decisions regarding data center architecture and design.<\/p>\n Below is a diagram of the model with a brief explanation of\u00a0the various components:<\/strong><\/p>\n Image provided by the author<\/em><\/p>\n Everything starts and is measured by the Service Level Agreements (SLAs) committed to an organization. This is true whether you\u2019re a fast-growing startup or a Fortune 500 company.<\/p>\n A strict definition of SLA would be a service that is well-defined and the delivery components (time, performance, resources, outcomes, etc.) are measured.<\/p>\n In practical application, SLAs can also be internal and unwritten, though still measured, as often is the case (email delivery may be a prime example) or external and managed by contract (outsourcing, co-location, and public cloud are examples).<\/p>\n Whatever is agreed to, however it is delivered, and however it is measured, IT is accountable for the SLAs.<\/p>\n IT Service Management (ITSM) refers to the activities and processes, often directed by policies, which are performed to deliver to the SLAs.<\/p>\n Focus is placed on the implementation, quality, and efficiencies of the services and the appropriate mix of people, process, and technology required. ITSM is often aligned to standards-based practices and frameworks like the\u00a0IT Infrastructure Library (ITIL<\/a>), Control Objectives for Information and Related Technology (COBIT)<\/a>, and others.<\/p>\n As public cloud delivery is simplified, increasing pressures mount for the same delivery efficiencies from on-premise assets.<\/p>\n Applications run on top of operating systems and infrastructure and perform functions aligned to fundamental and complex business processes.<\/p>\n Applications can be either systems or user-invoked. Applications can be hosted and delivered on premise as is traditional or served as a service hosted by the vendor provider. Many organizations are going through an application segmentation process to determine which application model best suits the particular business need.<\/p>\n Other trends in applications include mobile, where the app runs on a hand-held device, and increased workload portability with containers. Mobile applications reflect generational differences and bring new challenges for user experience and security.<\/p>\n Application containers like Docker<\/a> on Linux help abstract the operating system-level virtualization process. This gives administrators greater control over provisioning services, greater security and process restriction, and even more intelligent resource isolation.<\/p>\n Image credit<\/a><\/em><\/p>\n As applications and environments continue to virtualize and be exposed as discrete patterns or micro-services, the ability for enterprises to quickly create new composite applications and business services adds to the agility of the organization.<\/p>\n As we move towards Software Defined Data Centers (SDDCs), infrastructure elements \u2014 networking, storage, and compute \u2014 are virtualized and delivered as a service. ITaaS represents an outcome of SDDCs.<\/p>\n Virtualized IT assets are pooled and made available as required; efficiencies are gained by policy-based automation and managed as services rather than separate capabilities. Services are provided by self-service catalogs. Manual intervention is greatly reduced or even eliminated in some cases.<\/p>\n Transitioning to a SDDC model is an on-going process and is generally driven by cost and speed of delivery issues through unlocking the constrained value in the traditional processes. Automation standards supported by the majority of market leaders are emerging, like open source\u2019s OpenStack<\/a>.<\/p>\n Image credit<\/a><\/em><\/p>\n The implementation of virtualization and automation sets the foundation for building on-premise private clouds that deliver the efficiency of the public cloud model.<\/p>\n Orchestration aligns and implements business requests with the applications, data, and infrastructure to achieve a planned result.<\/p>\n Orchestration is the business process management mechanism that defines the policies and service levels through automated workflows, provisioning, and change management. This creates a business process, application-aligned set of services that can be scaled up or down based on the needs of each application.<\/p>\n Orchestration also provides centralized management of the resource pool, including billing, metering, and chargeback for consumption. Orchestration can be used for simple tasks like hardening servers to complex undertakings of deploying large ERP development and test environments.<\/p>\n Today\u2019s on-premise infrastructure comes in many varieties, including physical, virtual, siloed, and converged.<\/p>\n Many companies\u2019 data centers have a mixture of traditional delivery through siloed compute, storage, and network with rapid transformation to public cloud-like constructs of IT delivered as converged services.<\/p>\n The data center is also undergoing an ever-increasing shift to virtualization beyond compute to storage and network. As virtualization becomes more pervasive and we transition to software defined, we see a shift away from branded infrastructure to commodity, web-scale architectures relying more on the overarching software abstraction than the individual system capabilities. This commodity-based, software-driven model is emerging as hyper-converged, web-scale architecture.<\/p>\n Lastly we are seeing an increased interest to free the bound up value in manual process by automating and orchestrating services for agile provisioning of simple and complex services to maintain pace with the off-premise, public delivery capabilities.<\/p>\n This is the big snowball rolling downhill, gaining mass and momentum.<\/p>\n The clear leader is Amazon Web Services (AWS)<\/a>, with a host of other players including Microsoft Azure<\/a>, IBM SoftLayer<\/a>, VMware vAir<\/a>, etc. jockeying for position and market share.<\/p>\n Image credit<\/a><\/em><\/p>\n Public cloud offers simple and fast provisioning and de-provisioning, cost accountability, on-demand, self-service, and great efficiencies. The joke is cloud makes mistakes cheap and great ideas expensive.\u00a0You also can have virtual private clouds from a public provider, which\u00a0provides greater control and autonomy.<\/p>\n In a public cloud model, your data center is delivered in an Op-ex model instead of traditional Cap-ex. Most born-in-the-web companies use public cloud exclusively with emerging use cases of DR, dev\/test, and peak season bursting as leading business cases for the established enterprise.<\/p>\n Cloud can be viewed as revolutionary for the data center \u2014 or simply another delivery model to deliver to the SLAs.<\/p>\n This is the most commonly-used mechanism for delivering the hybrid enterprise.<\/p>\n Using a model from the SOA service bus design and leveraging API-led integration, connect from any point to any other point for linking applications, data, and devices.<\/p>\n Connect anywhere, on-premises or in the cloud. Achieve full flexibility with a hybrid architecture and extensibility to connect future technologies.<\/p>\n Emerging solutions leverage policy and templates to simplify and streamline integration so workloads are transparent and mobile. Maybe we all can get along!<\/p>\n Every data center has a set of utilities used to monitor and maintain the health and resiliency of the services delivered to the SLAs.<\/p>\n Ultimately clients are looking for that \u2018single pane of glass\u2019 that will monitor all services, the automated cockpit from which we can manage the services based on policy, and the high availability of systems so services are consistently delivered.<\/p>\n This becomes a more distinct reality as we move towards the software defined data center and systems become self-healing, though we are a long way away from this dream as most NOCs would demonstrate.<\/p>\n IT Security is playing\u00a0an increasingly prominent and pivotal role within every organization today. Prominent as IT Security has become a consumer awareness issue that is in the media and affecting our lives almost daily. Pivotal as it is now a cornerstone to most organizations\u2019 risk management programs as it cuts to the core of an organization\u2019s profitability and brand.<\/p>\n Organizations are responding to IT security and risk management with a dual focus. The first is the traditional technology response to make sure data, identity, and assets are secure using a model of prevent, detect and respond, and recover.<\/p>\n![\"Screen](\"http:\/\/d1vqbpto5tbbz0.cloudfront.net\/blog\/wp-content\/uploads\/2015\/06\/23205700\/Screen-Shot-2015-06-23-at-3.23.25-PM.png\")
