Editor's Notes
A New IT Plan: Enterprise DevOps PaaS, APIs, and Ecosystems Open source PaaS, Open APIs, and Open Ecosystems are accelerating agility, empowering developers, and enabling innovative business strategies. In this session, Chris will describe how Enterprise DevOps PaaS technologies increase developer velocity and reduce iteration times; where Open APIs are empowering developers by delivering business building blocks; and why teams are embracing long tail development communities that enable innovative business ecosystem strategies. A pragmatic, open source driven game plan will demonstrate New IT approach vectors.
n the abstract, business agility can be defined as your ability to rapidly change business vectors. A business vector is your business speed and direction. The direction may lead into new markets and new products, or engaging with new participants. Reducing time to IT solution delivery increases your team’s ability to adjust the business vector and match business opportunity.With adequate instrumentation, IT delivery agility can be quantified. Consider the following agility metric recommendations:Time to create project workspaceTime to build, integrate, testTime to approve, promoteTime to deploy, releaseDwell time – time waiting for the next operation to commence or completeAfter application project inception and before coding commences, systems administrators must create project workspaces. How long does your team wait before gaining access to source code management repositories, requirement management projects, and defect tracking projects?Moving code through build, integration, and test tools is often a time and labor-intensive process. The entire team waits while applications assets are built, integrated, and tested. When teams use iterative development processes, the wait time aggregates over several hundred or thousands cycles. How long does your team wait during build, integration, and test phases?When one team member finishes a task and the work enters an approval phase, how long does the team wait? After the work is approved to move through phase gate, how long before the project is promoted into the next phase?
Cloud platforms exhibiting Cloud Native PaaS architecture provide an opportunity to increase business innovation and creativity. Cloud native platform solutions shield teams from infrastructure details and inject new behavior into the application.Cloud native PaaS architecture requires infrastructure innovation in provisioning, service governance, management, deployment, load-balancing, policy enforcement, and tenancy. Cloud native, innovative provisioning infrastructure increases tenant density and streamlines code deployment and synchronization. Multi-tenancy within middleware containers enables teams to customize applications and services per consumer by changing run-time configuration settings instead of provisioning new instances.A Cloud platform may automate governance and enforce policies (i.e. security, service level management, usage) through enterprise PaaS services. Cloud provisioning may fulfill enterprise deployment requirements across all service providers and technologies used by solution delivery teams.To re-invent the platform and achieve benefits, new Cloud Native platform architectural components and services are required. Traditional client-server and N-tier web application architectures do not exhibit requisite cloud characteristics (i.e. elastic scalability, multi-tenancy, resource pooling, or self-service). Figure 1 below depicts the new Cloud Platform architectural components and services. The PaaS controller layer deploys, scales, monitors, and manages an elastic middleware Cloud. PaaS Foundation services provide common solution building blocks. A complete, comprehensive, and Cloud-aware middleware container layer delivers new cloud-aware capabilities to business applications.The middleware container layer should not be tightly coupled to the PaaS foundation. Acartridge or droplet pattern is used to support running any application or service container on the PaaS. By providing a cartridge plug-point, Cloud Native PaaS environments can run any language, framework, or server (after appropriate integration via the cartridge API and agents).Elastic Load BalancerElastic Load Balancer (ELB) balances load across cloud service instances on-premise or in the cloud. The ELB should provide multi-tenancy, fail-over, and auto-scaling of services in line with dynamically changing load characteristics. Cloud Native Elastic Load Balancers are tenant-aware, service-aware, partition-aware, and region-aware. They can direct traffic based on the consuming tenant or target service. Cloud Native Elastic Load Balancers manage traffic across diverse topologies (i.e. private partitions, shared partitions, hybrid cloud), and direct traffic according to performance, cost, and resource pooling policies. A Cloud Native ELB is tightly integrated with the Service Load monitor component and dynamically adjusts to topology changes. Service Load MonitorThe Service Load Monitor component acquires load information from multiple sources (e.g. app servers, load balancers) and communicates utilization and performance information to an Elastic Load Balancer responsible for distributing requests to the optimal instances, based on tenant association, load balancing policies, service level agreements, and partitioning policies. When the level of abstraction is raised above Infrastructure as a Service (IaaS) instances, Teams no longer have direct access to specific virtual machines. New Cloud Native components are required to flexibly distribute applications, services, and APIs across a dynamic topology. A Cloud Controller, Artifact Distribution Server, and Deployment Synchronizer perform DevOp activities (i.e. continuous deployment, instance provisioning, automated scaling) without requiring a hard, static binding to run-time instances.Cloud ControllerA Cloud Native Cloud Controller (or auto-scaler) component creates and removes cloud instances (virtual machines or Linux containers) based on input from the Load Monitor component. The Cloud Controller right-sizes the instance number to satisfy shifting demand, and conforms instance scaling with quota and reservation thresholds (i.e. minimum instance count, maximum instance count). The Cloud Native Cloud Controller may provision instances on top of bare metal machines, hypervisors, or Infrastructure as a Service offerings (e.g. Amazon EC2, OpenStack, Eucalyptus).Artifact Distribution ServerThe Artifact Distribution Server takes complete applications (i.e. application code, services, mediation flows, business rules, and APIs) and breaks the composite bundle into per-instance components, which are then loaded into instances by a Deployment Synchronizer. The Artifact Distribution Server maintains a versioned repository of run-time artifacts and their association with Cloud service definitions.Deployment SynchronizerThe Deployment Synchronizer checks out and deploys the right code for each Cloud application platform instance (e.g. application server, Enterprise Service Bus, API Gateway). With infrastructure and servers abstracted and encapsulated by the Cloud, a Cloud Native PaaS Management Console allows control of tenant partitions, services, quality of service, and code deployment by either Web UI or command-line tooling.Cloud Native PaaS Architecture Business BenefitsCloud Native PaaS architecture accelerates innovation, increases operational efficiency, and reduces cost.The traditional, keep-the-lights-on, operational run-rate consumes precious resources and limits innovative new projects. By optimizing project footprint across pooled resources on a shared Cloud Native PaaS infrastructure, Responsive IT can reduce operational spend, improve total cost of ownership (TCO), and make more projects financially viable. Multi-tenant delivery models create an efficient delivery environment and significant lower solution deployment cost. For more information on the financial benefits of multi-tenant, Cloud Native platforms, read the white paper.By building a Cloud Native PaaS environment, you provide your teams with a platform to rapidly develop solutions that address connected business use cases (i.e. contextual business delivery, ecosystem development, mobile interactions).

Agile and DevOps principles must be applied across a cross-functional team and the entire lifecycle (e.g. project inception, design, development, deployment, and management).Operations activities related to deployment and release management often hinders agility and time-to-market. The level of effort required to deploy a real-world application is often non-trivial. Continuous deployment technology automates operations activities and replaces manual intervention.While dwell time sounds cozy and refreshing, excessive wait states and downtime between activities diminishes team efficiency and engagement. Automated notifications eliminate dwell time between hand-offs. Automated project workspace creation, Cloud environment provisioning, and on-demand self-service access reduces wait time between software development phases.A DevOps focus on continuous activity execution (e.g. continuous build, continuous integration, continuous test, continuous delivery) creates a ‘no wait’ environment. Teams do not have to wait for the next script to run or for the next activity to commence. By incorporating automation into developer and operations processes, teams bypass time consuming manual tasks and gain faster phase execution. Both DevOps and PaaS promote simple, on-demand self-service environments that shield team members from complexity and reduce skill hurdles. By offering on-demand self-service access, rapid business innovation and experimentation is possible. By reducing complexity, team members are not required to obtain special training and skills before consuming IT services and infrastructure.To read more about Enterprise DevOps PaaS accelerating team agility, read a recent blog post.
Traditional application PaaS (aPaaS) environments do not help organizations build apps, but simply serve as a cloud run-time environment. DevOps PaaS brings no waits, faster phase execution, widespread accessibility, rapid grassroots innovation, and increased resource availability to IT projects.DevOps PaaS delivers development, test, and production run-time clouds that are integrated into development workspaces containing source code management, defect tracking, requirements management, test automation frameworks, and continuous build. Figure 2 describes the infrastructure topology underlying a DevOps PaaS.By automating software activities, workflow, and phase approval gates, a DevOps PaaS decreases software development and delivery times. A rapid IT timeframe closely matching today’s fast business-pace will accelerate revenue growth and enhance customer retention rates. A New IT model driven by DevOps PaaS will expand development team participation, lower IT cost, and increase business agility.Recommended ReadingDevOps Meets ALM in the CloudPaaS Performance MetricsMulti-tenant, shared container PaaS TCOWSO2 App Factory Product Page

By hosting all business partners as tenant applications within a multi-tenant environment, the ecosystem environment more readily aggregate and share business information.IT focus and responsibility shifts towards creating an ecosystem delivering composable and reusable IT capabilities. Project teams can access open APIs, services, business processes, open data, and applications and compose the assets into new solutions. The operations model safely shifts the center of project responsibility to project individuals and business units while maintaining IT as a more valued business partner. IT maintains responsibility for policy compliance, serves as a trusted technology advisor, and mentors teams on IT capability usage. Corporate IT delivers ‘solution accelerator packs’ that decrease time to market, reduce development hurdles, and cost effectively implements corporate policy.
Open APIs are empowering developers by delivering business building blocks.Teams can rapidly compose solutions to meet shifting business demand by re-using Open Data and Open APIs. Teams are embracing long tail development communities that enable innovative business ecosystem strategies to emerge, with Open Data and Open API foundations.In a New IT operations model, instead of being a single-purpose delivery team, IT serves as a broker and validator of solution building blocks.Manage APIs for external value chain and customer use in mobile Apps.

PaaS increases agility by democratizing access to IT infrastructure and services. PaaS environments based on multi-tenant, shared application containers facilitate pervasive access by increasing tenant density and lowering tenant cost.PaaS increases agility by democratizing access to IT infrastructure and services. Offering a low cost environment and increasing resource availability, PaaS promotes democratized access. The chosen PaaS environments must offer required application building blocks available on-demand, and minimize cost by amortizing infrastructure expense over multiple project teams. PaaS environments based on multi-tenant, shared application containers facilitate pervasive access by increasing tenant density and lowering tenant cost. Affordable, pervasive on-demand access encourages project teams to use approved PaaS environments and enables shadow IT teams to efficiently and safely create a long tail of application development projects.Adopting an Open Enterprise DevOps PaaS can align your IT model with business agility expectations.DevOps principles and practices combined with PaaS characteristics will quicken IT solution development and delivery. A DevOps focus on continuous activity execution (e.g. continuous build, continuous integration, continuous test, continuous delivery) creates a ‘no wait’ environment. Teams do not have to wait for the next script to run or for the next activity to commence. By incorporating automation into developer and operations processes, teams bypass time consuming manual tasks and gain faster phase execution.

By offering on-demand self-service access, rapid business innovation and experimentation is possible. By reducing complexity, team members are not required to obtain special training and skills before consuming IT services and infrastructure.
When defining a roadmap to align IT’s pace with business agility expectations, establish IT team objectives that quicken IT solution development and delivery, offer new technology as on-demand shared services, and enhance your team’s ability to rapidly satisfy emerging business use cases (e.g. social collaboration, mobile application connectivity, ecosystem partnering).Open source PaaS, Open APIs, and Open Ecosystems are accelerating agility, empowering developers, and enabling innovative business strategies. In a recently published white paper, I describe how adopting a New IT plan can create a responsive IT team.The path to New IT requires moving away from traditional application platforms, traditional team structure, and traditional information flows. Responsive IT teams are adapting their infrastructure, processes and tooling to re-invent the application platform and re-think application delivery. The New IT architecture underlying Responsive IT intelligently incorporates Cloud Platforms, BigData Analytics, Enterprise DevOps, and API first development.
