TIPS, INSIGHTS AND THE LATEST FROM THE EXPERTS BEHIND CAKEPHP

Quick glossary: DevOps

Has your team gotten you down with the use of so many terms that seem so unfamiliar? Don’t despair! The ability to rapidly develop, deploy and integrate new software is essential to success - but you should be aware of the terms that the dev ops team will be using!

First starting off with devops - which is a mash-up of two terms: "software development" and "information technology operations. But there are more

A/B testing

A technique for testing new software or new features whereby two or more versions are deployed to users for testing. The metrics from each variant are then compared and assessed based on the testing criteria.

Acceptance testing

The testing performed near the end of the development cycle that determines whether software is ready for deployment.

Agile development

Agile development refers to a methodology that emphasizes short iterative planning and development cycles. The idea is that iterative development affords more control and establishes predictability.  

Behaviour driven development

A development methodology that asserts software should be specified in terms of the desired behavior of the application, and with syntax that is readable for business managers.

Build Automation

Tools or frameworks that allow source code to be automatically compiled into releasable binaries. Usually includes code-level unit testing to ensure individual pieces of code behave as expected.

CA Release Automation

CA Release Automation is an enterprise-class, continuous delivery solution that automates complex, multi-tier release deployments through orchestration and promotion of applications from development through production.

Continuous delivery

Continuous Delivery is a set of processes and practices that radically removes waste from your software production process, enables faster delivery of high-quality functionality and sets up a rapid and effective feedback loop between your business and your users.

Deployment Manager

Cloud Deployment Manager allows developers to easily design, deploy, and reuse complex Cloud Platform solutions using simple and flexible declarative templates. From simple web servers to complex highly available clusters, Deployment Manager allows teams to spend less time managing, and more time building.

Delivery pipeline

A sequence of orchestrated, automated tasks implementing the software delivery process for a new application version. Each step in the pipeline is intended to increase the level of confidence in the new version to the point where a go/ no-go decision can be made. A delivery pipeline can be considered the result of optimizing an organization’s release process.

Functional testing

Testing of the end-to-end system to validate (new) functionality. With executable specifications, Functional Testing is carried out by running the specifications against the application.

Gitlab

GitLab is a web-based Git repository manager with wiki and issue tracking features. GitLab is similar to GitHub, but GitLab has an open source version, unlike GitHub.

Github

GitHub is a web-based Git repository hosting service, which offers all of the distributed revision control and source code management (SCM) functionality of Git as well as adding its own features. Unlike Git, which is strictly a command-line tool, GitHub provides a web-based graphical interface and desktop as well as mobile integration.

Lean

“Lean manufacturing” or “lean production” is an approach or methodology that aims to reduce waste in a production process by focussing on preserving value. Largely derived from practices developed by Toyota in car manufacturing, lean concepts have been applied to software development as part of agile methodologies. The Value Stream Map (VSM), which attempts to visually identify valuable and wasteful process steps, is a key lean tool.

Micro services

Microservices is a software architecture design pattern, in which complex applications are composed of small, independent processes communicating with each other using language-agnostic APIs. These services are small, highly decoupled and focus on doing a small task.

NoOps

A type of organization in which the management of systems on which applications run is either handled completely by an external party (such as a PaaS vendor) or fully automated. A NoOps organization aims to maintain little or no in-house operations capability or staff.

Non-Functional•Requirements (NFRs)

The specification of system qualities such as ease-of-use, clarity of design, latency, speed, ability to handle large numbers of users etc. that describe how easily or effectively a piece of functionality can be used, rather than simply whether it exists. These characteristics can also be addressed and improved using the Continuous Delivery feedback loop.

Orchestration pipeline

Tools or products that enable the various automated tasks that make up a Continuous Delivery pipeline to be invoked at the right time. They generally also record the state and output of each of those tasks and visualize the flow of features through the pipeline.

Whitebox testing

A testing or quality assurance practice which is based on verifying the correct functioning of the internals of a system by examining its (internal) behavior and state as it runs.

Simplicity is important - here’s why

When it comes to web design, simplicity is not valued enough. Simplicity is important - but why? Simplicity reduces navigation confusion, makes the website look more sophisticated and can help in increasing site conversions (sign ups, contacts). All too often, web designers tend to miss the point of simplicity and over do the amount of information given on a single page - the need to get everything across at once can seriously hinder how much a website visitor is able take in. Over complicated pages can lead to higher than average bounce rates or lower on-page conversions. We thought we’d share with you some top tips to simplify your website.

  • Keep things along the 80-20 rule
    • Use the Pareto principle which is that 80% of the effects come from 20% of the causes. This means taking away as much as you can from your design that will not lead to any type of conversion. Take things back to the bare essentials and make those work properly
  • Embrace few colors in your theme
    • Does a monochrome color scheme work for you? If not, try out as few colors as possible. Work towards a design that requires less effort for your website visitor to process. Fewer colors will also give your site a sleek, classic look
  • Keep copy short and sweet
    • Embrace compelling copy but keep things shorter and to the point. Make your point quickly and keep things easy-to-read by sticking to a few key points. Use shorter sentences, and keep paragraphs to a maximum of 3-4 sentences for easy reading.
  • Fix your navigation
    • Often many sites have over complicated and lengthy navigation options. Remember to include navigation to your list of things to simplify today. Keep important and key pages in your navigation bar. Remove excess clutter and keep all navigation menus visible. Other key things to keep in mind is the use of universal icons as well as ensuring a sitemap in your footer - these are all standard items that visitors look for.

How Much Does it Cost to Design a Site?

If you are in the market for a website or application, it can sometimes be daunting. Being unsure of where to start, which development firm to use or how much the whole process is going to cost you can be truly overwhelming. And then there are those horror stories of others, who selected a developer based solely on cost (the cheapest quote perhaps) and ended up majorly down the hole with their budgets, while owning a unfinished website. Whether you are in the market for a website application with a specific outline and goal, or have a rough idea of what you need your application to do, how do you go about finding the best selection for you? And then how do you know that whoever you select is going to deliver what you want and in the time frame that you need it? And then, not knowing how to code yourself, you can land up frustrated at not understanding the process - especially if your development team gives you the runaround.

What your website users are trying to tell you

Every visitor to your website has a goal in mind - this may not be a conscious goal, but they are visiting your site for a reason. So listening to your users feedback is key to meeting their expectations! As a business owner, be sure to keep these in consideration and as a developer, be sure to pass these recommendations through to your clients. What are some things that users are trying to tell you and how do you find out? What and why is it Often people forget about the basics and fail to include what their product, service or business is. By excluding this vital information there will be users who will not know what the purpose of the page that they have stumbled upon is, but what to do next - and therefor bounce quickly off of your site. Where is your pricing information? If you are trying to sell something - a product or a service - be sure to include the price information as this is used by your visitor to determine their next action. Even if you are providing resources in return for their details, it is important to be clear. Where are those testimonials or reviews? Have others tried it People like to know that whatever they are investing money into is worth it - reviews or customer testimonials help to show your visitors what you can do. Be sure to add this information in a way that is easy for you visitors to find. Where can I sign up or contact you Another vital piece of information that many often forget is to let your visitors know how to signup and contact you. Perhaps you have chosen to hide your contact information due to spam bots or other issues faced, however, if you are in the business of recruiting clients, then be sure to have some form of contact information easily available to your visitors.
