Top 3 Approaches to Legacy System Modernization

Aggregated on: 2022-02-15 11:04:58

Your system is putting your business at risk and you haven’t fixed it. Don’t touch what isn’t broken, right? Well, while that may be currently working for you, you are walking down a slippery slope. Legacy systems for long-term business operations come with many risks, and it may be time for a change. We will discuss ways to move on from legacy systems to put your business in a better position. Define Your Legacy System There is no standard or generally accepted definition of a legacy system. When talking about legacy systems, age is not the first point of consideration. While this may be a factor, it is not always the case because newer systems and software can be classified as legacy systems.

DevOps - Overcoming the Struggle

Aggregated on: 2022-02-15 10:04:58

Everyone is ‘doing’ DevOps, but only a handful of people are getting the business value they expect. Why? The reason is very simple, those who are getting the business value know exactly what to focus on in getting the DevOps model right in the organization. They also know that business value is the ultimate goal of DevOps, and value begins and ends with the customer. There are 4 key elements to get DevOps right in an organization. They are not only simple but the most ignored aspect. DevOps would be highly effective in bringing the business value to the customers if and only when these things are followed effectively. Here are the 4 key DevOps components: 1. Leadership 2. Organization structure 3. Value stream mapping (VSM) in DevOps 4. Pulse-Check Leadership Leadership – the most uttered word in all organizations and industries today. My greatest inspiration for leadership comes from the leadership guru “John C Maxwell” and John says, “Everything raises and falls on leadership”. DevOps is no exception to it and in DevOps world, “Leadership” is the most overstated but under practiced phenomena today. “People buy-into the leaders before they buy-into their vision” – John Maxwell Before people in the organization follow any worthy vision or causes, they are keen to follow “worthy leaders” first. People in the organization do not buy into DevOps vision just because it is worth doing it or it is the “in-thing” to do it, until they buy-into the leaders first. So, the primary reason for DevOps success or failure in an organization is totally dependent on the leaders of the organization. Characteristics of DevOps Leader Here are some key characteristics every DevOps leader must focus on to have: Influencing According to John Maxwell, “Leadership is influence, Nothing more nothing less”. DevOps leader must have the influencing skills to be effective in the organization. People Focused Rather than Privilege Focused No-one becomes leader automatically by the privilege or the title they have. Leaders need to be people centric and value them all the time. People don't care how much you know until they know how much you care. Creating DevOps Culture DevOps is a culture and the whole organization needs to be doing DevOps for it to be successful. Without the right mindset and culture, it’s hard to realize the full benefit of DevOps. It is the responsibility of the leader to create the right culture. Patience A greatest virtue, a leader can possess. DevOps transformation do pose lots of uncertainty and leaders true characters are seen based on how they can handle the tough times and showcasing patience. See Beyond Possibilities Leaders don’t just cast vision, but they are visionaries themselves. Leaders not only see things before anyone sees it, but they also see more than others see it Organization Structure An advantage of the functional structure is that grouping jobs by skills and knowledge and clear roles and responsibilities. However, the disadvantage is that each functional departments may become too siloed, often losing sight of the organization as a whole. Why This Siloed Structure Wouldn’t Work for DevOps DevOps is owned by just 1 division head in the organization, and he/she would need to sell or justify this service to the rest of the organization. There is always seller-buyer dynamics between DevOps division head & other division heads. Not all the division heads are having the same level of KPIs to rollout DevOps. Unfortunately, It’s the direct responsibility of this 1 person to promote DevOps for the entire organization. No synergy between DevOps teams and the rest of the organization as they are mostly operated in Silos. Other enabler teams like Infrastructure, operations, tooling are not always together with DevOps teams in this structure. Most of all, business don’t see the value in DevOps and they are always seen as additional overheads/cost in this type of organization structure. Recommendations Like any other scrum team, DevOps team should be a permeant scrum team in the organization. it is important to create a cross functional team for DevOps. Appoint a product owner for DevOps. This person should have direct access to the organization leaders to influence the roadmap for DevOps. DevOps scrum team should be the combination of DevOps, engineering, tooling, architecture, infrastructure, operations and required business representation always. This cross functional setup should be replicable & increased to more number of scrum teams as the demand increases. Topmost leadership in the organization should own up driving DevOps. As DevOps requires Cultural shift in the organization, it should be driven top-down. DevOps success should be the KPI of CIO in the organization. VSM in DevOps Seeing is Believing - Value streams are a visual tool that enables organizations to objectively measure and track what is most important to the organization and what they believe will actually bring value to customers. Measuring End-to-End Flow Flow Metrics measure the flow of business value through all the activities involved in the process. It clearly represents the bottleneck in a end-to-end value stream and helps to determine the area to focus and improve. When we measure a subset of the flow, such as the time it takes for developers to complete an “user story” or the time it takes to deploy the changes to production, we can optimize that segment of the value stream

How to Overcome 4 Challenges in IoT Hardware Design

Aggregated on: 2022-02-15 00:04:58

Getting a new Internet of Things (IoT) product on the market requires understanding design challenges that could pose obstacles along the way or mean the device does not work as well as expected. Here are some of the main concerns related to hardware and how to solve them. 1. Long Battery Life Many of today’s IoT device users need them to have batteries that can last for years. That’s particularly important if someone plans to deploy something in a remote area they cannot easily access for battery changes. Suppose the product is a connected medical device used inside a patient’s body. Frequent battery replacements could require operations or otherwise put someone at an elevated risk of complications.

Modernizing a Legacy Microsoft .NET Application by Upgrading It to the Latest Microsoft .NET Core Framework

Aggregated on: 2022-02-14 20:34:58

Business Statement Recently I was working as a cloud migration architect to migrate several on-premise applications to Microsoft Azure Cloud. During the portfolio analysis, we found that many of the on-premise applications were created long ago by using very initial versions of the Microsoft .NET Framework. The frameworks in these applications were already at the end of their lifecycles and it would not be easy to get any support for those frameworks. These frameworks were also not supported on Azure Platform as Service (PaaS) offerings.

Highlights From the 2021 State of DevOps Report

Aggregated on: 2022-02-14 18:49:58

The State of DevOps report released by Puppet each year is a great indicator of the pulse of the DevOps movement at the time. With its 10th edition, the report has continued to focus on the key challenges faced by organizations and solutions to them. This report digs deeper into these issues and provides great insight for organizations that want to move to higher levels of DevOps maturity. This post covers the key points of the report. Stuck in the Middle The report has previously shown the percentage of organizations in the low, mid, and high DevOps maturity, and usually, the midsection makes up the biggest chunk. This year is no different with 80% of organizations in the mid-level of maturity. Interestingly, this time the report breaks down this midsection into three sub-categories: low-mid, true-mid, and high-mid.

Enter the Cloud Native Dojo: Blackbelt-Level Debugging

Aggregated on: 2022-02-14 16:34:58

Debugging is often viewed as an art form or a craft. This is true for most engineering-related troubleshooting processes (e.g., the art of motorcycle maintenance). We’re usually indoctrinated into the basic moves by a senior developer and are then thrown into the proverbial pool. As a result, even senior engineers sometimes have gaps in their debugging skills. There are very few university courses or books on the subject, so it’s really hard to blame them. In his book, “Why Programs Fail — A Guide to Systemic Debugging”, Andreas Zeller told a story from his youth working at a computer store. A customer walked into the store with a new Commodore 64 computer. For context: The computers back then booted directly to a basic interpreter; basic would accept line numbers as the first argument. He tried inputting this valid basic line:

Understanding System Logger

Aggregated on: 2022-02-14 15:04:58

December was not a good time for Java developers and even less for Ops. The former had to repackage their apps with a fixed Log4J's version, and the latter had to redeploy them - several times. Yet, every cloud has a silver lining. In my case, I learned about System.Logger. In short, System.Logger is a façade over your logging engine. Instead of using, say, SFL4J's API and the wanted implementation, you'd use System.Logger instead of SLF4J. It's available since Java 9, and it's a bummer that I learned about it only recently.

How To Use Props in Vue

Why Sustainability in Software Engineering Matters

Aggregated on: 2022-02-13 23:19:57

Tech managers often focus on immediate achievements instead of real impact. They are proud when employees work late and believe it equals productivity. In reality, this approach is counterproductive. Sustainable software development yields much better results. It’s a comprehensive approach to optimizing the SDLC, finances, and human resources during software engineering and use. Sustainable software also means minimum harm to the environment, which is critical given that by 2040, ICT will account for 14% of the global carbon footprint.

Continuous Feedback Is Key To Taking Your AI From “Good to Great”

Aggregated on: 2022-02-13 22:19:57

Deploying AI instantly brought value and growth to many businesses. However, it is well established that sustaining the value over time, not to mention maximizing it, could be quite challenging. Continuous optimization is the key to successful AI deployments. Begin with a product that’s good enough, learn from how it performs in the real world (especially as the data environment changes), and then improve; then learn and improve again, and so on. It’s a bit of an obvious insight, but it is rare for AI-driven products to be perfect from day one. To accomplish continuous optimization you need continuous feedback. You need “eyes and ears” observing your data and models and telling you whether they’re performing well. That’s easier said than done, for various reasons. These reasons are outlined below.

Meet Josh (a pseudonym). Josh is your typical developer. He’s good at writing code in his native language, hates documentation, and REALLY hates the “drag and drop” approach to developing software found in bloated API management platforms. Josh would rather write code, weave in some docs and avoid worrying about security, networking, deployment, and reliability. Josh avoids venturing into newer networking technologies like Istio, labeling them unnecessarily complicated to configure and maintain. He would rather write everything in Java, Groovy, or his go-to integration library: Apache Camel. Recently Josh stumbled across an open-source API platform called Kong. After 30 minutes of playing around, Josh discovered how easy it was to:

5 CDK Lessons Learned

5-Step Strategy for Optimizing Slow Tests

Aggregated on: 2022-02-13 17:04:57

Professional software development is a feedback-based process — each new iteration is informed by past results. Feedback is powered to a considerable degree by tests. Slow tests affect development. Engineering teams lose momentum and become frustrated because they can’t meet their goals. A slow test suite puts the brakes on CI/CD, making release and deployment more difficult. This often means that organizations can't ship out products on time, and risk losing their competitive edge.

Website Accessibility Testing Checklist

Accessibility Testing is a software testing technique that checks if a website or app is easily usable by every user on the internet, including individuals with disabilities or special needs. Often considered a sub-category of usability testing, it ensures that specific, unchangeable conditions do not prevent a person from accessing online resources as easily as anyone else. Accessibility testing is significant and should be included in testing pipelines for two significant reasons:

Fixing Common AD Security Issues With BloodHound FOSS

Aggregated on: 2022-02-13 16:34:57

Active Directory (AD) is Microsoft’s identity and access management software that controls which users have access to the systems and resources on a network. It’s a popular target for attackers because getting control of AD allows them to deploy malware, steal sensitive information or do other nasty things in a way that’s very difficult for defenders to detect or block. Making AD more secure involves fixing security flaws within the environment that allow attackers to get in - but first defenders need to identify what those flaws are. AD’s built-in tooling makes it very difficult to see which users have privileges to which systems and objects. So many security issues, even very dangerous ones, simply go unnoticed.

Cloud-Native Compilation: Bringing JVMs Into the Modern Cloud World

Aggregated on: 2022-02-13 16:04:57

Across the industry, companies are trying to rein in runaway cloud costs by squeezing more carrying capacity out of the instances they run in the cloud. Especially in the Java space, developers are trying to fit workloads into smaller and smaller instances and utilize server resources with maximum efficiency. Relying on elastic horizontal scaling to deal with spikes in traffic means that Java workloads must start fast and stay fast. But some antiquated features of the JVM make it hard to effectively utilize the resources on your cloud instances. It’s time to re-imagine how Java runs in a cloud-centric world. We started by exploring how compilation can be optimized by offloading JIT workloads to cloud resources. Can we achieve optimized code that is both more performant and takes less time to warm up?

GitHub Is Bad for AI: Solving the ML Reproducibility Crisis

Aggregated on: 2022-02-13 16:04:57

There is a crisis in machine learning that is preventing the field from progressing as fast as it could. It stems from a broader predicament surrounding reproducibility that impacts scientific research in general. A Nature survey of 1,500 scientists revealed that 70% of researchers have tried and failed to reproduce another scientist’s experiments, and over 50% have failed to reproduce their own work. Reproducibility, also called replicability, is a core principle of the scientific method and helps ensure the results of a given study aren’t a one-off occurrence but instead represent a replicable observation. In computer science, reproducibility has a more narrow definition: Any results should be documented by making all data and code available so that the computations can be executed again with the same results. Unfortunately, artificial intelligence (AI) and machine learning (ML) are off to a rocky start when it comes to transparency and reproducibility. For example, take this response published in Nature by 31 scientists that are highly critical of a study from Google Health that documented successful trials of AI that detects signs of breast cancer.

Cybercrimes are growing swiftly in the world of digitalization in both senses; complexity and rate of recurrence. In the idea of being resilient in an impulsive environment, an organization’s cyber security has to be updated with the latest technologies to protect IT Assets and Infrastructure setup. The old school security methodologies cannot be an answer for new-age sophisticated cybercrimes. The organization having a robust cybersecurity resilience strategy in place is a must that enables the continuity of business processes in all situations (before, during, and after a cybersecurity incident). As per the research conducted by Cybersecurity Ventures in 2021, there will be one company that falls victim to a ransomware attack every 11 seconds.

Hyper-Automation — New Age Automation With AI

Active minds look to obviate monotony. This is the seed of the greatest ideas that have ever transpired. Ideas that lead to progress, growth, and freedom from doing things manually. Over the past several decades, the advancement in technology has given us the greatest gift of all, time. Time to focus on our creative endeavors and leave it to the machines to carry out the tasks that our brains now consider mundane. As a species, it is our constant endeavor to make our lives easier and more convenient. While the core meaning of “automation” remains the same, the usage of the word has truly changed over time. We have come a long way from manually switching on the ceiling fan to automatic temperature control in air conditioners everywhere. Things that we perceived as “automated” years ago, kept getting more and more automated and became more convenient to use. This is largely due to advancements in technology over the years.

I had a customer inquire whether an existing cluster with Kerberos authentication can allow non-root users to authenticate using cert instead of using GSS API. Given the layered pg_hba.conf design influenced by Postgres, we should have no trouble accommodating this use case. I find the topic of Kerberos very interesting and my colleagues commonly refer to me for help with this complex topic. I am by no means an expert at Kerberos, I am however familiar enough with it to be dangerous. That said, I've written multiple articles on the topic which you may find below:

Cloud Systems (Part 3): Deploying to Amazon ECS

Aggregated on: 2022-02-12 19:19:57

Cloud engineering is taking over software development. In a lot of ways, this is great; it allows us to build and deploy more complicated applications with less difficulty, and maintaining those applications becomes less troublesome too. We can release smaller updates more quickly than ever, ensuring that we can stay on top of feature requests and security issues. That said, the rise of cloud engineering has also introduced a lot of complexity in the form of dozens of services even within just one cloud provider. Figuring out where to start can be tough, so let’s take a practical tour! In this series, I’ll walk you through building a personal website and deploying it using modern cloud engineering practices. Elastic Container Service In the previous tutorial, we extended our personal website to use the Flask web framework, add server-side routing, and package everything up into a Docker container. It’s still only running locally, though, and we want to deploy it. To do that, today we’ll be learning to use Pulumi to deploy to Amazon’s Elastic Container Service. If you completed part two of this series, we’ll be picking up right where we left off. If you’re just now joining me, you can get the completed code by forking and cloning this repository.

ArgoCD: Managing a GitOps Flow for Kubernetes Clusters

Aggregated on: 2022-02-12 17:34:57

Introduction ArgoCD is a GitOps Continuous Delivery tool for Kubernetes. It automates the deployment of desired application states to target environments. The main idea of GitOps is to have declarative descriptions of the desired state of production in a Git repository like source code and an automated process to match these desired and current states of production. It allows developers to push commits to the repository whenever they make deployment to the production environment while the automated system handles everything else. This is where ArgoCD comes into the picture. It completes the most crucial step of GitOps by ensuring that the repository and production environment states are always in sync. Furthermore, it reports and visualizes any deviation and provides mechanisms to automatically or manually sync the live state to the desired target state.

Detect Untagged PDFs for Accessibility

PDF documents come in a lot of different shapes and sizes. Unfortunately, many PDF libraries do not optimize PDF documents for accessibility, which helps people with disabilities use screen readers to reliably read PDF content. Untagged PDFs do not meet many of the legal standards of accessibility, and PDF tagging is often overlooked when documents are published. Adobe PDF Services can be used to identify PDF documents that are not tagged. Using the Adobe PDF Services connector in Microsoft Power Automate allows you to get metadata about your PDF documents that can help flag documents and determine what processing you need to complete on the PDF.

The glass morphism effect is popping up all over the web at the minute. Although in the past it was generated mostly with images, we can now achieve the same result using CSS. The CSS glass morphism effect is pretty widely supported as well. Below, I've created a generator so you can make your own CSS glass morphism effects and add them to your applications and websites. CSS Glass Morphism Generator A little while ago I used the CSS glass morphism effect to create some apple UI elements. To show how this effect works a little better, I've created a CSS glass morphism generator below. You can change the options, and generate your own glass morphism along with code.
