Software is at the core of every modern business, and software-driven companies are disrupting most traditional industries. As the demand for rapid delivery in digital services grows, companies are looking for ways to release products and upgrades in weeks instead of months, or in days instead of weeks. Many DevOps groups are adopting the continuous integration/continuous delivery/continuous deployment cycle of Agile software development to address the high velocity of releases and faster time-to-market requirements. In the CI/CD/CD cycle, developers and testers continuously integrate and test new code, deliver applications and upgrades to production, and from there, deploy them to customers through cloud- or web-based venues.
But in most companies, dev/test teams are dependent on IT and operations (IT Ops) teams to provide the physical and software stacks they need, and IT Ops teams can’t provide developers and testers with infrastructure and applications fast enough to meet the ongoing and relentless pace of the CI/CD/CD cycle.
DevOps Challenges
The most common IT Ops obstacles are long procurement and provisioning cycles, lack of automation and organizational silos.
Long Procurement and Provisioning Cycles: In many software companies, the IT Ops team has a lengthy procurement and provisioning cycle, and developers may have to wait anywhere from several days to a few weeks for IT Ops to handle each request.
Lack of Automation: Developers may be using an outdated IT ticketing system to request infrastructure and software. Each time a developer issues a ticket request, an IT Ops person must follow a certain workflow to fulfill that request, and must complete each step before sending the ticket on to the next IT Ops person in the chain. These workflows often consist of time-consuming manual steps. For example, an IT admin may spend hours manually copying database software from a file server over to the hardware using command line interface (CLI) scripting. The admin must then install and configure the database software and connect it to the network.
Organizational Silos: In large enterprises, individuals or sub-teams fulfill certain tasks for a dev/test request separately from the others. These silos turn IT Ops procurement into a long series of handoffs, where each team member must complete their assigned tasks before handing the job off to another team member.
What’s a company to do? The answer is to implement a self-service, automated private or hybrid cloud. Here are some of the reasons for this approach.
On-Demand, Self-Service Provisioning
Every developer is different, and each should have the power to create their own workspace. A self-service cloud automates the provisioning process by letting developers and testers manage their own initial deployments and configurations. The cloud platform should offer a set of automated provisioning tools to allow developers and testers to create their own dev/test environments. The cloud solution should include both a self-service user interface and an API-driven infrastructure-as-code that lets developers create VMs and databases, access storage, set up network connections, etc., using RESTful API coding.
An Intelligent, Well-Organized User Interface
A self-service cloud should have an intelligent user interface (UI) that gives developers access to a set of common infrastructure tools and applications. Ideally, a self-service UI should allow IT Ops administrators to assign resources in an organized manner. Admins should be able to designate business units (BUs) on the UI (i.e. “AppDevTeam1,” “WebDevTeam1”) based on units within the company, assign team members to BUs, and designate current projects (i.e. “AppDevProject1”) on the UI according to BU. They should also be able to assign quotas to each BU (i.e. AppDevTeam1 gets 100 VMs, 25 vCPU cores, 100GB memory and 400GB storage), and to each individual project (i.e. AppDevProject1 gets 10 VMs, 5 vCPU cores, 8GB memory and 40GB storage).
An Application Store
A self-service private cloud should have an online “application store” that provides single-click access to common tools and services for CI/CD, workload management, middleware and storage back-ends.
Seamless, Two-Way Hybrid Cloud Migration
A self-service hybrid could should have seamless, two-way migration to allow developers and testers who have public cloud access to easily move applications and workloads back and forth between public and private clouds.
Administrative Dashboards
A self-service cloud should have a set of administrative dashboards that allow the IT Ops team to control access to resources on the UI. These dashboards should deliver complete visibility into which teams and team members are using which resources, and allow the IT Ops team to perform admin tasks such as:
- Creating user accounts and passwords on the UI
- Creating BUs, and projects for each BU, on the UI
- Assigning developers and testers as “members” of a certain BU or project
- Assigning self-service infrastructure tools (compute, storage, network) on the UI, and set quotas for those tools according to BU or project
- Importing new applications to the application store or the UI.
A Software-as-a-Service Platform
A software-as-a-service (SaaS) platform with portal-based access is the best venue for a self-service cloud solution. A SaaS platform offers the flexibility to do upgrades and customization to the various features of the UI, application store and administrative dashboards. The flexibility of the SaaS private-cloud solution gives it the potential to become the de facto standardized platform for CI/CD/CD in Agile software development.
In short, DevOps teams need to keep up the CI/CD/CD pace in a modern enterprise, and self-service cloud platforms offer the self-provisioning and customized workspaces that keep developers productive and happy.
