DevOps Tools Introduction #02: Modern Software Development

January 16, 2018 - by Fabian Thorns

The DevOps Tools Engineer exam starts with objective 701.1 which covers modern software development, including aspects of architecture and team organization. These are broad topics but, since LPI expects candidates to be experienced IT professionals, you will probably already have some background in this area. Therefore, we’ll focus on those aspects which are explicitly mentioned in the exam objectives.

The context of the exam is applications that follow modern approaches to software development. One of the most quoted sources related to this kind of applications is the Twelve-Factor App. This manifesto explains twelve best practices for designing software that runs in containers and clouds. These tips apply to any programming language and development ecosystem. After reading them, you should think about how to implement these best practices with your preferred language and platform. Try to reflect upon how your software handles the Twelve Factors.

When getting more detailed in your learning, Martin Fowler's website is a great place to learn about software architecture. He and his co-authors offer articles on application architectures, SOA and microservices, immutable servers as well as monoliths and coupling.

A topic of special interest in the world of services are application programming interfaces; APIs for short. The exam objectives explicitly mention REST APIs and JSON data. A great introduction to APIs can be found on restful.io. Likewise, jsonapi.org illustrates how to represent data in JSON and links to documents explaining JSON in greater detail.

The exam objectives also mention a number of security aspects of applications. A good learning source is the Open Web Application Security Project. They cover the terms mentioned in the objectives such as cross-site scripting, SQL injections, web service security, authentication, transport encryption, CORS and CSRF, and error reports. Make sure you get an overview of the materials offered by OWASP and take a good look at their collection of cheat sheets.

Two other terms mentioned in the exam objectives are ACID properties and CAP theoremes. Although there are many explanations, a number of answers to the question of the relationship of these terms are given in a quora thread. This discussion also covers properties of relational and NoSQL databases; a field that we will shortly meet again when talking about cloud services.

Finally, topic 701.1 also expects you to understand agile software development and DevOps. The Manifesto for Agile Software Development is the canonical source for a lot related techniques. Again, Martin Flower’s website hosts articles on the agile manifesto and DevOps culture as well as some hints on how to become fluent in agile.

Learning about architectures and development techniques involves a lot of reading and almost no coding. It is a dusty topic for sure. However, the contents of this topic build the base upon which all of the other topics of the exam can be placed. In their own way, each technology covered in the exam supports the architectures and collaboration models explained in this objective. Having this big picture in mind helps you to recognize the relationships between the tools and explains design decisions made by the creators of the tools covered in the exam. Therefore, bookmark the most useful texts you found when working through the links above. Review them at the end of your studies and see how the technologies you’ve learned in the meantime fit in.

To see some examples of practical applications of these principles, stay tuned for next week’s posting, when we’ll talk about cloud components and platforms.

DevOps Tools Introduction #01: Getting ‘Getting Started’ Started

January 9, 2018 - by Fabian Thorns

In October 2017, LPI released the LPIC-OT DevOps Tools Engineer certification. Covering a series of relatively new tools used to develop and deliver software in a collaborative manner, the content of this exam extends skills of both software developers and system administrators.

While candidates with a background in either of these knowledge domains will find the tools covered in the exam useful, it can be difficult to gain proficiency with these tools. For all of them, documentation exists, although it sometimes is overwhelming and it is difficult to find a good starting point.

This posting is the first in a series of introductory postings in the LPI blog. Together we will take a tour through the LPIC-OT DevOps Tools Engineer’s objectives. For each topic I will summarize the most important tools and skills and will point you to documentation you might find helpful to get started.

To work through the upcoming postings and prepare yourself for the DevOps Tools Engineer exam, you should be equipped with a few tools:

  • Print out the exam objectives and get some color markers. It might sound silly, but keep in mind that the objectives ultimately describe what is relevant in the exam and what is not. Following the objectives makes sure you spent your time efficiently. Work with the objectives, check what you already know, color what you want to repeat.
  • Get a place to keep notes. You should be prepared to be asked for commands or configuration options in the exam. They won’t be obscure hidden ones, but those you frequently need when working with these tools on an ongoing basis. Take notes of anything you consider relevant, give your notes some structure and remember that you will come back to these notes for repetition once your exam date gets closer.
  • Prepare your computer to run some virtual machines. You’ll need a few gigabyte of space and virtualization software. Some of the tools we cover use VirtualBox by default, so that might be a good choice to start. You can, of course, use any other virtualization software you like, although, it might require some tweaks to the examples that are provided by documents referenced in this series.
  • Sign up for an account at an IaaS cloud provider. Most of the large providers should be fine, some even offer you free access to small computing instances. This should be sufficient for your first experiments. If you already have access to a cloud computing platform, make sure you have some extra dollars in your account to play around with some instances. In case you want to do all your learning in the cloud without using local virtual machines, you’ll definitely need some more dollars for larger instances and the ability to use them concurrently.

This series of blog postings contains links to external learning materials. These are, of course, only recommendations. If you have another favorite source for a topic just stick to that. If you are already familiar with a topic, you’ll probably already know some of the content in the referenced documents. In either case, make sure you meet the requirements LPI outlines in the objectives. No matter how you prepare yourself, enjoy learning new tools and spend some time considering how you can leverage these tools in your daily job.

Please feel encouraged to share your recommended learning resources in the comments. We will collect and review these links and add them along with the original blog postings to our wiki.

If you’d like to join our tour through the DevOps tools jungle, make sure you come back to our blog next week, when we’ll learn more about modern software development.

How to Close the UK’s Tech Skills Gap

December 15, 2017

Every year, technology becomes more integral to our lives and a larger contributor to the UK economy – with open source technologies driving the biggest growth in the technology marketplace today. However, it’s widely acknowledged that the UK is experiencing a significant IT skills shortage. The answer? Skills certification.

In the UK, there’s huge employer demand for tech specialists, with more developers, systems administrators and DevOps personnel needed across every industry. Advancements in software development have led to the rapid expansion of this sector.

There are now more than 29,000 software development companies in the UK - an increase of 150% in the past five years. The ever-increasing adoption of software and solutions based on open source technologies, such as Linux, is playing a vital role in the rapid growth of the tech industry and its global impact.

As Linux has now been adopted by corporate giants like Google, Facebook and the US Government, this global trend towards open source means an increased demand for skills in open source technologies.

A recent survey carried out by the Linux Professional Institute (LPI) of 200 UK IT employers finds that nearly 89% report difficulties in recruiting the right candidates for IT positions. Furthermore, 82% state that the shortage of suitable IT professionals is having a negative impact on their organisation.

The implications of this shortage on the UK economy are serious. There is a real risk that more jobs will be off-shored, or even that businesses will move their entire operations overseas. How can the industry prevent this from happening?

IT skills certification can help, by enabling employers to hire candidates with proven advanced, professional-level IT skills in Linux and other open source technologies. Certification provides accredited evidence of these skills, ensuring employers have access to a trusted talent pool of highly skilled and qualified IT professionals.

For a more in-depth analysis of the UK IT skills gap, read our new whitepaper: The IT Skills Gap

Testimonial: How Adam Futureproofed His Career with Linux Professional Institute

Testimonial: How Adam Futureproofed His Career with Linux Professional Institute

Linux Professional Institute (LPI) has delivered over 500,000 exams to IT professionals around the globe. So why do so many choose the world’s largest, vendor-neutral Linux and open source certification body to help advance their career?

According to Foote Partners report, ‘IT Skills and Certification Index’, there’s double-digit growth in bonuses paid to LPI certified candidates1. So, is it the promise of a lucrative career, or is there even more to being certified with LPI?

We asked Adam, from Washington, about his experience of getting into open source, taking the exams and how this contributed to his current success.

“After spending most of my early life learning and then teaching Spanish, Japanese and English as a foreign language, I realised that there wasn’t much progression in this profession – so decided to take a different path.

“I’ve always been interested in technology trends and saw potential in learning a programming language, so began learning about Linux in around 2007. I really felt that, if I was going to establish a new career in software development, that I had to understand and be able to work with Linux, first and foremost. Since I lacked any industry experience I decided to take the LPIC-1 and Linux Essentials certifications.

“I had to upskill to prepare for the exam, and I began by using Linux Academy and their training tools; I read lots of “Intro to Linux” books and study guides; I went to meetups and networking events to talk about Linux with people who really knew their stuff. To support my learnings with practical application, I set-up and ran my own Linux server, and started my own professional blog, which I still run to this day.

“The exams were actually much tougher and more thorough than I had expected, but that shows it’s something worthwhile. I’d recommend dedicating at least an hour a day to prepare for the exam.

“It took me approximately a year to complete all three exams (LPIC-1 [101 and 102] and Linux Essentials) but within a week of getting my first Linux certification, I got a job as a Support Technician, at Silicon Mechanics – where I currently work, but now as a Senior Support Technician.

My day-to-day work usually involves my using Linux in some way – so the certifications have helped me enormously. I’d definitely recommend it as a good foundation for anyone interested in an IT career – in fact, I have recommended it to colleagues who have also gone on to take the LPI exams.

For my own next step, LPIC-2 is on my list: I’m always looking to learn more about my industry and the LPIC-2 exam will allow me to take my knowledge to that next level – ultimately, enabling me to better support my customers.

Technology is always evolving, which makes it a fascinating industry to work in. We also now have an automation and DevOps team at Silicon Mechanics, and I’ll soon be joining up with that team and working with them on a number of projects. Once I take my LPIC-2 exam, I’m looking forward to taking the LPIC-OT: DevOps certification, so I can upskill in that area too.”

Exploring DevOps Tools - How to Choose the Tools Right for You

November 29, 2017

The popularity of the DevOps movement has resulted in a wide range of tools in the marketplace; the XebiaLabs DevOps Tool Chest alone lists over 200 different individual tools. And while DevOps is about more than just which tools you use, they are essential to benefiting from the improved speed, agility, and automation that DevOps offers.
 
To choose the DevOps tools that are most appropriate for you, your projects, and your organization, it makes sense to begin with exploring how they are categorized.
 

How DevOps Tools are Categorized
 
The types of tools emerge directly from the activities required to deliver software to users via the Continuous Delivery (CD) pipeline model. Each stage in the CD model corresponds to an activity in the software development lifecycle which moves software from development towards production.
 
Every software team’s CD pipeline – or toolchain – is a mirror of their software development processes, which means there are many possible configurations. DevOps principles involve collaboratively delivering high-quality software, and that means that tools naturally fall into more than one category because they are used throughout DevOps teams. Having said that, there are tool types that are common to all pipelines. These are: build tools, test tools, deploy tools, and monitor tools.  

DevOps ‘Build’ Tools
 
‘Build’ tools assist in the creation of the software, and they make up the beginning stages of all pipelines. Included under this category are tools for pulling source code from Version Control Systems (VCS), handling build-time dependencies among components, and building entire software products. Such tools automatically send reports if any errors are encountered and prevent software changes from moving down the pipeline. It is, by far, the largest category of DevOps tools.

DevOps ‘Test’ Tools
 
To ensure quality, automated testing is a vital stage of the CD pipeline. These tools test whether or not software features work as expected, previous software ‘bugs’ have reappeared (through regression testing), and check that performance is maintained. Failing tests should prevent software from reaching further stages, but the severity of the test failure is taken into account.
 
DevOps ‘Deploy’ Tools
 
Once code changes have passed all the quality checks from testing, they are packaged and tagged for release, and deployed to the production environment. This stage incorporates all tasks required to configure and provision the target environment, and install the software on the machines.
 
Deployment tools are increasingly working directly through cloud services to automatically create and configure virtual machines. The steps for creating the environment are increasingly written as code, giving rise to the term Infrastructure as Code.
 
DevOps ‘Monitor’ Tools

Once the latest code is running in the production environment, its operation needs to be monitored for signs of bugs, performance issues, and anything negatively impacting the user experience. Issues appear when users are engaging with the software, and therefore it is important to capture information through logging, alerting, and performance monitoring for analysis. DevOps monitor tools capture this data.
 

How to Choose DevOps Tools
 
With these categorizations in mind, here are the items you should consider when reviewing, evaluating, and choosing DevOps tools that will be right for you, your projects, and your organization:

Common Considerations (across all DevOps tools)

  • Track record of the tool working across different projects of various sizes and complexity
  • Time and/or cost involved in getting team members up-and-running on the tool – taking into account project deadlines and budgets
  • The expected return on investment, cost-savings, or cost-recovery expected from the tool.
  • The ability of the tool to integrate seamlessly with other tools along the Continuous Delivery Pipeline
  • The tool’s ability to keep project/client data secure (i.e within project groups or the organization)

Category-Specific Considerations

For ‘build’ tools – consider the programming language and runtime environment of your software product.

For ‘test’ tools – consider the scale and type(s) of testing you are conducting, e.g. functional testing, performance testing, accessibility testing, data testing, security testing, etc.
 
For ‘deployment’ tools – consider the reliability you need and whether a master-client or decentralized model would meet the requirements of your production environment.
 
For ‘monitoring’ tools – consider the degree to which they support your software architecture and their scalability.

Knowing the categories of DevOps tools and key considerations should help you optimize your DevOps processes and its outcomes.
