How DevOps oils the Value Chain

DevOps ? a clipped compound of development and operations – is a way of working whereby software developers are in a team with project beneficiaries. A client centred approach extends the project plan to include the life cycle of the product or service, for which the software is developed.

We can then no longer speak of a software project for say Joe?s Accounting App. The software has no intrinsic value of its own. It follows that the software engineers are building an accounting app product. This is a small, crucially important distinction, because they are no longer in a silo with different business interests.

To take the analogy further, the developers are no longer contractors possibly trying to stretch out the process. They are members of Joe?s accounting company, and they are just as keen to get to market fast as Joe is to start earning income. DevOps uses this synergy to achieve the overarching business goal.

A Brief Introduction to OpsDev

You can skip this section if you already read this article. If not then you need to know that DevOps is a culture, not a working method. The three ?members? are the software developers, the beneficiaries, and a quality control mechanism. The developers break their task into smaller chunks instead of releasing the code to quality control as a single batch. As a result, the review process happens contiguously along these simplified lines.

This is a marked improvement over the previously cumbersome method below.

Write the Code ? Test the Code ? Use the Code
? Evaluate, Schedule for Next Review ?

Working quickly and releasing smaller amounts of code means the OpsDev team learns quickly from mistakes, and should come to product release ahead of any competitor using the older, more linear method. The shared method of working releases huge resources in terms of user experience and in-line QC practices. Instead of being in a silo working on its own, development finds it has a richer brief and more support from being ?on the same side of the organisation?.

The Key Role that Application Program Interfaces Play

Application Program Interfaces, or API?s for short, are building blocks for software applications. Using proprietary software-bridges speeds this process up. A good example would be the PayPal applications that we find on so many websites today. API?s are not just for commercial sites, and they can reduce costs and improve efficiency considerably.

The following diagram courtesy of TIBCO illustrates how second-party applications integrate with PayPal architecture via an API fa?ade.

The DevOps Revolution Continues ?

We close with some important insights from an interview with Jim Stoneham. He was general manager of the Yahoo Communities business unit, at the time Flickr became a part. ?Flickr was a codebase,? Jim recalls, ?that evolved to operate at high scale over 7 years – and continuing to scale while adding and refining features was no small challenge. During this transition, it was a huge advantage that there was such an integrated dev and ops team?

The ?maturity model? as engineers refer to DevOps status currently, enables developers to learn faster, and deploy upgrades ahead of their competitors. This means the client reaches and exceeds break-even sooner. DevOps lubricates the value chain so companies add value to a product faster. One reason it worked so well with Flickr, was the immense trust between Dev and Ops, and that is a lesson we should learn.

?We transformed from a team of employees to a team of owners. When you move at that speed, and are looking at the numbers and the results daily, your investment level radically changes. This just can’t happen in teams that release quarterly, and it’s difficult even with monthly cycles.? (Jim Stoneham)

The Cloud: Changing the Game for Small Businesses

There is a consensus among cloud experts that the onset of cloud computing will benefit small organisations the most. In fact, many even go as far as saying that the cloud and small businesses are a match made in IT heaven. How much of this is true and how much of this is merely part and parcel of the hype surrounding cloud computing?

The Cloud as the Great?Equaliser

If you closely examine the essential characteristics of cloud computing, particularly public cloud services, you will see why small organisations would be very interested in the cloud, and would eventually flock to it, like moths to a flame. And why not? Cloud computing is turning out to be the weapon that can allow small and medium organisations to compete on a more level playing field against large enterprises.

Here are some cloud computing benefits that may just close the gap between the two.

  • Significantly lower IT spending. With little to no investment at all on hardware infrastructure and practically zero maintenance costs, SMBs that would have required substantial capital for IT are now finding it easy to get a business started from scratch or develop and test out new products by using the cloud as the backbone of their IT set-up. The pay-as-you-go pricing scheme that cloud computing offers allows companies to start small and scale up as needed, or when the revenue starts coming in.
  • Higher employee productivity. Licensing fees for software applications can run high even if you don’t have a large staff. Good thing there are now a host of cloud-based office tools – word processors, spreadsheets, presentations, accounting systems, etc. – that can boost employee productivity without the corresponding costs that small businesses can ill afford. Plus, team members in remote locations can continue to collaborate with the rest through any internet-connected device in real time.
  • Easier, better communication. The easy accessibility of communication apps has also changed the way employees interact with fellow employees and more importantly, with customers. Whether through email, instant messaging, or social networks, cloud services have given individuals and businesses more ways of giving and getting feedback. The best thing about it is that most of these services don’t cost much or are even free, giving SMBs ample tools to create better products and improve service.
  • A Look at the Figures Many small businesses are already seeing the potential in the cloud, with SaaS (Software as a Service) applications most commonly used among the early adopters. These services include email and other communication apps, file sharing, and backup.

In a February 2012 Edge Strategies survey (commissioned by Microsoft) of 3,000 small businesses in the US, the following data came to light:

  • The number of small companies with 2 to 10 employees using paid cloud services will triple in the next three years;
  • Current cloud users report purchasing an average of 4 services in the cloud now and expect to use 6 in the future;
  • Fifty percent agree that cloud computing is going to become more important for businesses such as theirs.

Further, a survey of 323 SMBs recently released by social business site Spiceworks and sponsored by EMC reveals that from 48 percent at the start of 2012 and 28 percent a year ago, 62 percent of the businesses surveyed now use some type of cloud app.

What these numbers show is that cloud adoption among small and medium enterprises is starting to gain ground and for sure, more will do the same as understanding and awareness increase. Yes, these businesses should still perform their due diligence as there is no one-size-fits-all cloud solution. But for those companies who have managed to find the right cloud apps and services for their needs, it’s all sunny skies up ahead.

Virtualisation

Using an IT solution that can provide the fastest (but still reliable) disaster recovery process is essential for the success of any business continuity plan. Although virtualisation is still considered leading edge technology by many business continuity specialists, it definitely brings a promise that, once fulfilled, can result in the cheapest, fastest, and most comprehensive solution for business continuity.

One great advantage of virtualisation over traditional BC (Business Continuity) methods is the relatively cheaper cost needed to achieve a certain level of business continuity assurance. Thus, more companies will find it easier to reach their required minimum for BC assurance. By contrast, some BCPs (Business Continuity Plan) based on a physical environment require companies to invest more than what they are willing to in order to reach the same minimum level of assurance.

Virtual machines, which can already encapsulate your operating systems and their corresponding applications, can be transported as a file from one machine running a compatible hypervisor to another. This makes the business continuity tasks of backup, replication, and restoration simpler and faster.

As of 2008, about 54% of IT professionals in Europe were willing to implement virtualisation within a maximum of two years. Furthermore, the expected compound annual growth rate of installed virtualised servers from 2008 to 2012 is already pegged at 33%.

If you want your organisation to take advantage of the benefits of this revolutionary technology, we’d be more than willing to help you discover what it can do for you. Then once you decide to make that transition to virtualisation, we can guide you every step of the way.

  • As not all applications are suited for virtualisation (e.g. some are too demanding on I/O and memory access), we’ll start by reviewing your entire IT system to see which portions can be implemented on a virtualized environment.
  • Using virtualisation and replication, we can conduct disaster recovery tests using up-to-date data without interrupting operations in your main IT site. Running these tests will increase your team’s preparedness and will allow you to discover possible weak points.
  • Provide a simple but comprehensive protection and backup system that encapsulates not only data, but also system configurations and application installations. This kind of setup allows for faster and easier disaster recovery operations. Because of these same characteristics, you can enjoy zero downtime while performing scheduled maintenance operations.
  • Since virtual machines are hardware-independent and transparent to operating systems, we can help you run a mix of legacy and new systems as well as open source and proprietary systems, allowing for more flexibility in your BCP budgeting.

Saving Energy Step 1 ? Implementing a Management System

There has been much hype down the years regarding whether management is art or science. Thankfully, where people are concerned the pendulum has swung away from standard times in sweatshops in the west. However, when it comes to measuring physical things like harvest per square meter and the amount of energy consumed there is no substitute for scientific measurement, and this implies a system.

Managing energy cost and consumption down is like any other strategy. American engineer / statistician / management consultant W. Edwards Demming may have passed on in 1993. However he was as right as ever when he said:

  1. When people and organizations focus primarily on quality, this tends to increase and costs fall over time.
  1. However, when people and organizations focus primarily on costs, costs tend to rise and quality declines over time.

Demming believed that 90% of organizational problems arise from systems we put in place ourselves. This can be because we are so accustomed to them that we fail to notice when they are no longer relevant. The currently prevailing laissez faire towards energy is a case in point. What is managed improves and what is not, deteriorates. We know this. Let us take a look at how to apply this principle to energy management.

First, you need to get the subject out the closet and talk about it. How often do you do this is your boardroom, and how does energy rank against other priorities? Good governance is about taking up a position and following through on it. Here is a handy checklist you may like to use.

  • Do we use a consistent language when we talk about energy? Is it electricity, or carbon emitted (or are we merely fretting over cost).
  • How well engaged are we as a company? Looking up and down and across the organization are there points where responsibility stops.
  • How well have we defined accountability? Do we agree on key performance areas and how to report on them.
  • Are we measuring energy use at each point of the business? When did we last challenge the assumption that ?we’re doing okay?.
  • Have we articulated our belief that quality is endless improvement, or are we simply chasing targets because someone says we should.

A management system is a program of policies, processes and methods to ensure achievement of goals. The next blog focuses on tools and techniques that support this effort.
