Enterprise Computing and the Public Cloud Dilemma

Aggregated on: Tue Feb 08 2022 15:49:54 GMT+0000 (Coordinated Universal Time)

About Public Clouds There is little doubt that Public Clouds provide increased speed, agility, scalability, and pay-as-you-go, consumption-based pricing. These are attributes that most enterprises are looking for who want to transform their business and adopt new business models with cloud speed. Most enterprises consider digital transformation as the underpinning for innovating and creating differentiated values. Enterprises also realize that modernizing IT infrastructure is a must for digital transformation, and that Public Clouds provide a great opportunity for infrastructure modernization. A large percentage of enterprises have some workload running on a Public Cloud. However, the adoption of Public Clouds for critical workloads in regulated industries such as Financial Services, Insurance, or Telecommunications has not kept pace with the growing use of Public Clouds by small and medium enterprises. There are a number of well-known start-ups that are born on the Cloud; however, there are very few enterprises that have widely adopted Public Clouds for their mission-critical workloads. Barriers to a whole-scale adoption of enterprise computing to Public Clouds are often cited around the need for an enterprise-grade, hardened computing environment that provides continued assurance around security, privacy, compliance with regulations, resiliency, and operational readiness. Public Cloud providers have good physical security in place, with readily available evidence, comparable to customers’ own data centers. Cloud providers are quick to act to emerging security threats for the pieces of the platform for which they are responsible. However, when it comes to application environments, it is typically considered the responsibility of the customer who owns the workload to handle the assurance around security and data protection. Conformance to controls is not always that robust. The focus of cloud providers in the past has been on providing varied low-cost computing platforms with a low barrier to consumption, and not necessarily on hardening the application workload environment for individual customers. Cloud providers have recognized the need for enterprise-grade environments and begun to certify their environments for enterprise-type workloads.

Creating Selenium Test Cases: A Tutorial

Aggregated on: Tue Feb 08 2022 03:34:54 GMT+0000 (Coordinated Universal Time)

Selenium has established itself as one of the most popular automation testing frameworks within the software engineering community. Comprising a suite of tools - viz. IDE, RC, WebDriver, and Grid - Selenium has quickly established itself as a market leader in the test automation sector. Selenium capitalized on the inadequacies of previously used frameworks like HP QTP, and Mercury’s Astra QuickTest which compelled users to write scripts in VBScript and were primarily intended for desktop-based tests. Its support of a variety of languages like Java, Python, C#, Perl, Ruby, .net, and PHP, has made it popular with individual testers and companies like Netflix, Google, HubSpot, and Fitbit among others.

A Guide to the Next JS Framework

Aggregated on: Tue Feb 08 2022 03:34:54 GMT+0000 (Coordinated Universal Time)

Next.js is a framework extensively used by TikTok, Twitch mobile, Nike, IGN, PlayStation, Marvel, and many others. It offers all the functionality we need to deploy our application in production, with a hybrid system with static pages and server-side rendered (SSR) pages. It has support for Typescript and can be deployed without having to configure anything. SSR Benefits (Next.js) Performance Isomorphic: Works on both server and client (browser) Build: Next.js in the build retrieves the necessary data and ejects HTML with React components. Static export: Compile static files to be able to upload to the server 0 config (No need to configure anything to deploy Next, however it has a very extensible config) Api routes Deploy with Vercel Next head: To modify the head part of the page to improve the SEO Typescript support Environment variables are used in the browser code, not just server code. Fast Refresh: New experience of hot reloading in React components Code splitting: loads chunk corresponding to the page path Comparison With Gatsby Gatsby is primarily used for building websites that generate static HTML content and web pages that have a fixed or predictable number of pages and stable content. An example might be an e-commerce site that has only 50 products available for sale.

Documenting Angular Components Using Storybook

Aggregated on: Tue Feb 08 2022 03:04:54 GMT+0000 (Coordinated Universal Time)

As developers, in our daily work, we like to find good documentation of the libraries and technologies we use. It is, therefore, our responsibility to leave our work well documented. Those who come after us to use it and/or continue it will appreciate it. At Apiumhub we are very fond of documenting our projects. There are many tools that allow us to write documentation in Markdown (.md) format, and some others that also allow us to document our UI components. Most of them are written for and focused on React. What happens then if we want to document the components of our Angular project?

How Monitoring and AIOps Delivers the Ultimate DevOps Platform

Aggregated on: Tue Feb 08 2022 00:04:54 GMT+0000 (Coordinated Universal Time)

When it comes to delivering software through a DevOps model, the primacy of the platform is increasingly evident. DevOps platforms are multi-tenant, self-service oriented, developer-centric, and are an essential component of a multi-cloud strategy. They provide guide rails and standardized tools and technologies for developers to build, test, and iterate with ease. A core component that must not be neglected when operating a DevOps model, however, is resilience. DevOps breaks down monolithic products into smaller value streams that can be delivered as independent cloud-based services. Once teams are set up to deliver under this model, it will be formalized through service level agreements (SLAs). To deliver against these, robust monitoring and alerting practices must be put in place. As with any DevOps practice, automation is the ultimate goal — and when it comes to monitoring and alerting, an AIOps platform is the gold standard.

In the first blog post, we learned about the fantastic symbols (debug symbols), how the symbolization process works, and lastly, how to find the symbolic names of addresses in a compiled binary. The actual location of the symbolic information depends on the programming language implementation the program is written in. We can categorize the programming language implementations into three groups: compiled languages (with or without a runtime), interpreted languages, and JIT-compiled languages.

Java Template Method Pattern in 3 Minutes [Video]

Aggregated on: Mon Feb 07 2022 22:04:54 GMT+0000 (Coordinated Universal Time)

The template method pattern is a behavioral design pattern in GoF's design pattern. In my opinion, it is fundamental and worth knowing and learning. It opens up our eyes to many of the usual ways of object-oriented design. In this pattern, the father class (the abstract superclass) defines the skeleton/algorithm of an operation in terms of a number of high-level steps. The detailed steps are to be implemented by the sons (the subclasses).

Python and Automation: A Perfect Combo

Aggregated on: Mon Feb 07 2022 17:04:54 GMT+0000 (Coordinated Universal Time)

Python is one of the most popular languages among data scientists, researchers, and academics. It systematically tops the ladder on TIOBE, Stack Overflow, and GitHub, being the rockstar among other coding languages. It has a rich library of tools that can be applied to solve various problems in the field of automation. Indeed, Python compares favorably in its ability to automate virtually any process. Python also has a lot of built-in libraries. Since many services provide their data via APIs, you will have the ability to write scripts to solve tasks without deep programming knowledge.

Simplifying CockroachDB Kerberos Architecture With a Load Balancer

Today, I'm going to try to simplify our architecture or at least management of Kerberos artifacts as they relate to CockroachDB by introducing a load balancer. Given the presence of LB, we can obfuscate the CockroachDB cluster architecture from Kerberos and ease the management of Kerberos keytabs as well as service principal names. Articles Covering CockroachDB and Kerberos 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:

The Principle Behind the Practice

Aggregated on: Mon Feb 07 2022 17:04:54 GMT+0000 (Coordinated Universal Time)

There are principles and there are practices. A principle is a universal truth that is applicable everywhere. A practice is a specific implementation of a principle and can vary based on the situation. Understanding the difference between the two is an important step in becoming wise. When you understand the principle behind the practice, you understand why we do the things we do. You understand the rules and also when to break the rules. Understanding the principle behind the practice helps you to be more flexible and apply good judgment in your day-to-day decisions.

The Open-Source Library to Improve Java Ability to Process Structured Data

Aggregated on: Mon Feb 07 2022 16:34:54 GMT+0000 (Coordinated Universal Time)

The general trend of contemporary Java application frameworks is towards the separation of data storage from data processing, aiming to be more maintainable, scalable, and migratable. One typical example is the currently hot microservices. The new framework requires that business logic, rather than performed in the database as the conventional framework designs, should be implemented within the Java program. On most occasions, the business logic in an application involves structured data processing. Databases (based on SQL) give a lot of support for the processing, enabling to implement business logic in a relatively simple way. Such support, however, has always been absent in Java, making it complicated and inefficient to implement the business logic with the language. As a result, development efficiency becomes sharply lower while the advantages of the framework are clear.

We would like to build a simple distributed robust Qiwi-like payment network system with enchanted audit and monitoring functionality. Specifically, we would like to allow an external agency to trace money transfers between "related" accounts and users. Also, the agency should be able to restore the whole transaction history of every account. The post is organized as follows. First, I elaborate on the functional requirements for our system. Next, I briefly discuss the Domain-Driven Design methodology. Then I define and discuss the CQRS and Event Sourcing concepts. Finally, I discuss how graph databases can efficiently detect cycles in directed graphs.

The Differences Between a Service Catalog, Internal Developer Platform, and PaaS

Aggregated on: Mon Feb 07 2022 15:04:54 GMT+0000 (Coordinated Universal Time)

There comes a time with many companies that build software to hit a handful of problems. One is keeping track of all the services and infrastructure they might need to deliver what they build. Another is when the need for environments to test code changes outstrips the capacity of operations teams to handle, and they look for ways to attempt to automate this but still have a modicum of control. Often teams in this position start thinking about or using Kubernetes or consider using infrastructure as code and look for a solution to solve internal deployment and discovery problems. Primarily large or fast-growing companies start looking for solutions and are faced with the question of building their own vs. buying. Even if you do extensive research, it's not easy to distinguish similar-sounding solutions. These include a platform as a service, a service catalog, or an internal developer platform, and they can, on the surface, sound similar. This post looks at some of these options to highlight the similarities, differences, and when or why you might want to use one.

Web3 and Decentralization: What it Means for Data Storage

Aggregated on: Mon Feb 07 2022 14:34:54 GMT+0000 (Coordinated Universal Time)

The recent explosion of web3 content, discussion, and debating seems to have happened overnight. Or, maybe we just recently started using the term to describe what we’ve been moving towards since the Internet was first conceptualized. Either way, there are already tons of great articles out there on web3 and blockchain technology. Instead, I wanted to dig a bit deeper into how web3 and decentralization are transforming my world: data storage. In case you need a refresher, web3 is basically the decentralized web - a group of technologies that are decentralized and used to create decentralized applications. Nader Dabit suggests that some of the characteristics enabled by web3 are decentralized web infrastructure ownership, native digital payments, self-sovereign identity, distributed infrastructure, and open backends. The pathway towards web3 is focused on becoming more independent. So, unlike web2 (which we’re in now), web3 means instead of a single company centralizing control, individual contributors own and control the underlying technology stack. In other words, web3 uses blockchains and distributed peer-to-peer networks instead of server-client relationships.

The Gilded Rose Kata in Rust

The Gilded Rose Kata is a refactoring exercise. The full description is available on GitHub. I became aware of the kata quite late, namely at the SnowCamp conference in 2016. Johan Martinsson and Rémi Sanlaville did a live-code refactoring based on the Gilded Rose. Nowadays, I think that the kata is much more widespread. It's available in plenty of languages, even some that are not considered mainstream, e.g., XSLT or ABAP. In this post, I'd like to do it in Rust. My idea is to focus less on general refactoring principles and more on Rust specifics.

Mulesoft has recently launched the Mulesoft Delivery Champion program to recognize Mulesoft architects with the ability to implement the Mulesoft Anypoint Platform at an enterprise scale. The completion of this program demonstrates the ability of a 360-degree Mulesoft architect who understands Best Practices, Mulesoft Catalyst IP, and Mulesoft Accelerators, along with Mulesoft Product Knowledge. This also measures an individual's skill in designing and presenting the detailed platform architecture based on business and Non-Functional Requirements. Since the Delivery Champion program is designed completely in a different way than any other Mulesoft Certification program (or for that matter, most of the Industry certification programs) so I thought sharing my journey to becoming a Delivery Champion might become some help for other Mulesoft architects aspiring for this Delivery Champion Program.

Connect External OpenSearch Dashboard to AWS OpenSearch Domain With Helm

Aggregated on: Mon Feb 07 2022 02:34:53 GMT+0000 (Coordinated Universal Time)

Last year, AWS announced the renaming of Amazon Elasticsearch Service to Amazon OpenSearch Service, with OpenSearch being the successor to the distributed search and analytics cluster service. Why Did Amazon Change From Elasticsearch to OpenSearch? On January 21, 2021, Elastic NV announced that they would change their software licensing strategy and not release new versions of Elasticsearch and Kibana under the permissive ALv2 license. Instead, Elastic is releasing Elasticsearch and Kibana under the Elastic license, with source code available under the Elastic License or Server Side Public License (SSPL). These licenses are not open source. Because of this, Amazon decided to create and maintain a fork from the last ALv2 version of Elasticsearch and Kibana. The fork is called OpenSearch and is available under ALv2.

Monorepo vs. Bill of Materials: Shaping Projects

Aggregated on: Sun Feb 06 2022 18:04:53 GMT+0000 (Coordinated Universal Time)

During most of my development career, the usual code organization pattern was monolithic repository or Monorepo. There is a single large version control repository, to which all developers on the project push their commits, sometimes breaking it. Every once in a while, this goliath is released as a set of artifacts. Before this may happen, all development activity ceases as we need to stabilize the code base and make sure every component is ready to be released. At Chronicle Software, our development efforts are structured around the Maven Bill of Materials (BOM) paradigm. At first, I met this technology with skepticism. Thirty-five git repositories instead of just one? Having to update dependency versions in a separate BOM repository just to test cross-module changes? There was suspicion that it would only create busywork. A bit later, I have changed my mind significantly.

An Engineering Team Journey From Component Tracks to Outcome Squads

Aggregated on: Sun Feb 06 2022 18:04:53 GMT+0000 (Coordinated Universal Time)

For any team, how the overall work is distributed into smaller tasks and how the team is constructed to tackle these tasks play an important role in determining the output, outcome, and efficiency of the unit, which in turn impacts the organizational goals and visions directly. Sometimes what may seem like an obvious strategy in terms of coalescing people with a similar skill/mindset has its own drawbacks in terms of resistance in building holistic units with complementing forces driven towards building a culture of risk-taking and innovation. If we treat teams as organisms, what you would want is an optimal balance across all its constituents organs ensuring a healthy being that is constantly progressing with self-sustained evolution and growth. Over the last couple of years, we at Symphony Talent had our own journey and learnings in building a balance within our engineering unit with a few macro and micro experiments wrt team topologies and squad structures. Felt it would be worthwhile to share our experiences over this period and the path it took to reach a model which improves our efficiency. To be honest, this is a constantly evolving process and the effectiveness of such a model is measured in terms of how quickly it can adapt to changing demands due to other factors at play.

Occasionally you might want to rename an AWS S3 bucket you are managing with Terraform. However, names of S3 buckets are immutable, which means you can’t change them directly. If you tried, Terraform would destroy the old one and then create a new one, resulting in data loss. To avoid this, you need to create a new bucket with the desired name, move the data over to it, make the relevant Terraform state replacements, and finally delete the old bucket.

Refactoring Infrastructure as Code

Aggregated on: Sun Feb 06 2022 11:04:53 GMT+0000 (Coordinated Universal Time)

The central principle of cloud engineering is adopting software engineering practices. Refactoring is a technique for making changes to code that improve maintainability, enhance performance, scalability, and security without changing its external behavior. In DevOps, refactoring often occurs with modern applications; however, we can apply those same techniques to cloud infrastructure with infrastructure as code. Refactoring results in many advantages. First and foremost, the code is more readable and easier to understand for other team members –this aids in maintainability and well-organized code, providing a solid foundation for future releases. Overall, if done well, refactoring reduces complexity which makes future changes more efficient.

There are many blog posts, articles, etc. about SC. This article answers a question that isn’t discussed that often: How will SC affect modularity in an Angular application?

Introduction In our day-to-day, and mainly, in the positions of full remote work, the dedicated time to achieve our tasks and objectives is covered with squalls of meetings (clients, troubleshooting, at a company or team level, dependencies with other people, etc.), and we forget some important factors such as: Communication and relationship: Of every monthly and weekly meeting; What percentage do I dedicate to strengthening my relationship with the team to get to know them better and know how they are doing, what motivates them, what concerns them, their hobbies, etc? Target: What is the purpose of the meeting? Personal to connect and build relationships with my colleagues or for work purposes? I have a 30-minute meeting to agree on estimates and 15 minutes have been for off-topic discussions. Time value: Is the meeting necessary or can the goal of collaborating asynchronously be met? I attended the meeting but, did I have something to contribute or did I learn something that will help me in the future? In this article, we will focus on the communication side, in which, besides strengthening, we will get feedback that will allow us to improve personally and as a team to also offer a better service and a better quality.
