Agile and the Cloud – Match made in Heaven!

Agile and the Cloud are both pervasive these days.  Agile is a software development method based on an iterative and incremental approaches. Applying an Agile method and mindset can, on the one side, can incrementally build Software as a Services (SaaS) based products and, on the other side, utilize IaaS (Infrastructure as a Service) and PaaS (Platform as a Service) to build the SaaS products and services.

As most software professionals are aware, the action of delivering the increment into the traditional on-premise software product environment is often laborious and time consuming. SaaS conveniently provides shared software products as services, and associated data via the Internet, a model that can be scaled and configured to a company’s or product team’s needs. SaaS changes the software paradigm by providing the software as a service “in the cloud” to people and companies that need that product or service. Companies no longer need local administrators to handle the rigorous and time-consuming effort of establishing on-premise product infrastructure and the installing the software.

When building products for the cloud, a production-ready environment is made available to teams almost instantly. While most products require an on-premise installation, building cloud products reduces the need for the often rigorous and time-consuming effort of installing the new releases of the software product infrastructure prior to the installation. Because Agile utilizes an iterative and incremental approach, SaaS products can be incrementally upgraded when the Sprint Review (aka, demonstration) indicates that the product is ready. The effort on the SaaS provider side is reduced also, because a few installations by experts are much easier to develop and manage than the many installations by customers (and documentation, ramp-up, and problem resolution that are included).

On the Agile side, the challenge is to build an infrastructure that supports Agile and does not impede the progress of the Agile team that must continue to deliver value. A simultaneous goal is to avoid investment in infrastructure that may not be needed in later phases of the project. One suggestion is to utilize the infrastructure envisioning approach, which applies an incremental approach to the continuous establishment of an effective infrastructure. This is where Infrastructure as a Service (IaaS) and Platform as a Service (PaaS) can be useful to Agile teams. The cloud IaaS and PaaS approaches enable consumers to only use and pay for what they need. This is a distinct advantage for incremental development processes like Agile. This "use-what-infrastructure-you-need" approach minimizes technology debt and allows the team to adjust and scale its needs just-in-time.

As Agile methods continuously build SaaS product increments (i.e. functionality), the cloud delivers them as increasing business value to the customer with little effort from the customer. In addition, the cloud (by way of IaaS and PaaS) provides Agile projects with tools and infrastructure just-in time, so that the team always has the tools and infrastructure they need but never wastefully invests in unused equipment. Consequently, they are able to provide continuous value to the customer in the cloud. This mutually beneficial relationship is a “match made in heaven” for project teams utilizing Agile to build software in the cloud and using cloud infrastructure to support Agile projects. 

Have you benefited with the Agile and Cloud relationship?  If so, in what ways?

Book released in the US - Adapting Configuration Management for Agile Teams

Exciting news! My book “Adapting Configuration Management for Agile Teams” which is on the world market is available in paperback and now as a Kindle ebook!  It is the first book of its kind that combines discussions on both CM and Agile. Agile is the facilitator of change while CM is the enabler of change. When done properly, CM provides the right level of control for Agile projects to maintain and increase its high level of velocity. CM for Agile can be a very powerful combination when done effectively.

How can it help you? Aimed at all levels of professionals in the Agile, Configuration Management (CM), Project Management, Product Management, and Development fields, this book provides very tangible support for Agile teams. It focuses on how CM with its practices and infrastructure can be adapted and managed in order to directly benefit Agile projects
What are some unique features of this book that can help you?

 • Provides both an Agile Primer and a CM Primer. For those experienced with CM, it provides a solid overview on Agile(or visa-versa on CM) so you can come up to speed. It can be great for someone who wants to learn both. It’s almost like a two-for-the-price-of-one book!

 • Provides insightful and concrete guidance on adapting CM for Agile methods while maintaining CM principles and allowing minimal structure needed for Agile projects to continue to run fast. Adapting CM for Agile doesn't mean throwing out the CM principles of identification, control, audit and report. Instead it means that CM should be adapted to allow the lean nature of Agile. The question is how do we do this? Inside, learn how to adapt:

o Continuous Integration and Build applying notions of bit-size tasks, right-sizing branches, minimizing merging, emphasizing continuous build, and testing with teeth.
o CM Planning (aka CM Vision) moving away from big-effort-up-front (BEUF) to a more evolutionary approach, applying an iteration 0 to get started, adapting CM roles and responsibilities, and using wikis and other CM formats.
o CM to support more effective Refactoring, Pair Programming, and Test Driven Development (TDD), Traceability, Baselines, Problem Management, CM Audit, and CM Reporting and lean metrics.
o CM support for Distributed Development for Agile teams when co-location is not an option by performing a distributed analysis and considering code access solutions, and supporting a Cloud infrastructure option.
o CM infrastructure for Agile thru implementing CM Envisioning for a brand new product following Agile methods or thru CM Refactoring to adapt CM for an existing product line moving to Agile methods.

• Will help you understand how the more modern CM features help with implementing Agile in an effective manner and that CM tools are a strategic Agile partner.
• Will help you understand how to more effectively support Agile when your organization, product, or project must align with standards and frameworks.

Again the book is called “Adapting Configuration Management for Agile Teams” (ISBN-10: 0470746637). This book is available on both the Agile and Wiley websites. Also, if you want the original CM book which people love as a great CM reference book, feel free to consider, “Software Configuration Management Implementation Roadmap” (ISBN-10: 0470862645).

Have a great day!

Infrastructure for Agile Teams - Who are some "in the Clouds" service providers?

Unlike the past where organizations and product lines spent considerable time and large amounts of capital to establish local infrastructure, the future presents us with other options. They include (but not limited to) renting infrastructure "in the clouds" (e.g., in the internet), owning the server and renting space "in the clouds" (hosting service provider), and owning everything locally and on-premise (within your company). Focusing on "in the clouds", there are several types of "in the Clouds" service providers that allow teams to quickly get infrastructure set for Agile teams.

For those wanting to rent or lease a cloud infrastructure, this is a more recent concept and option that some organizations are utilizing where the infrastructure (servers, software, etc.) is effectively in the internet cloud. This service is sometimes known as cloud computing but have a variety of other names each with slightly different focuses and approaches including software as a service (SaaS) sometimes known as the application service provider (ASP) model, platform as a service (PaaS), application infrastructure provider (AIP). Some companies that provide cloud infrastructure include Force.com, Right Scale, Rackspace, GoGrid, and Caspio Bridge. Not all provide the exact same set of services, but they each provide aspects of cloud infrastructure services. Consider performing a search on “cloud infrastructure” for more service providers.

For those wanting to avoid the cost of having a secure datacenter on premises, then can rent a space in the clouds. Co-location as a service refers to renting space in the clouds by a service provider in order to physically host your server or servers. This is slightly different from cloud infrastructure where you rent a service that provides you access to infrastructure without necessarily knowing the details behind it. For co-location services include ColoSpace, I/O Data Centers, Colocation.com and Peer1 amongst others. They all provide either strictly collocation services or co-location as part of their set of services. Since co-location is most advantageous when the service is within your location, it is best to perform a search on “co-location” and possibly your city or state.

As you consider each of these approaches, take a good look at the amount of your budget, need for control, and even the development methodology you are considering. These factors can help you better evaluate the best infrastructure model that is best for your needs.
