Mixing Kubernetes Roles, RoleBindings, ClusterRoles, and ClusterBindings

Aggregated on: 2023-10-02 16:16:55

At some point, as your Kubernetes cluster grows in complexity, the question of role-based security will become important. Typically, this means breaking the cluster up into namespaces and limiting access to namespaced resources to specific accounts. To support this, Kubernetes includes a number of resources, including roles, cluster roles, role bindings, and cluster role bindings. At a high level, roles, and role bindings are placed inside of and grant access to a specific namespace, while cluster roles and cluster role bindings do not belong to a namespace and grant access across the entire cluster.

Backend For Frontend (BFF) Pattern

Aggregated on: 2023-10-02 09:16:55

What is BFF? The Backend for Frontend (BFF) design pattern involves creating a backend service layer specifically tailored to the requirements of a particular frontend application or a set of closely related frontends. While traditionally this approach has been contrasted with a monolithic backend serving multiple frontends, it’s worth noting that a BFF can indeed serve multiple frontends, especially when tools like GraphQL (GQL) are utilized. The key is that these frontends have similar requirements and data needs. Regardless of the number of frontends, the primary advantage of the BFF is its ability to be optimized for the specific needs and context of its consumer(s). Here is an example of what could be architecture including a BFF pattern :

How to Debug an Unresponsive Elasticsearch Cluster

Aggregated on: 2023-10-01 17:31:54

Elasticsearch is an open-source search engine and analytics store used by a variety of applications from search in e-commerce stores, to internal log management tools using the ELK stack (short for “Elasticsearch, Logstash, Kibana”). As a distributed database, your data is partitioned into “shards” which are then allocated to one or more servers. Because of this sharding, a read or write request to an Elasticsearch cluster requires coordinating between multiple nodes as there is no “global view” of your data on a single server. While this makes Elasticsearch highly scalable, it also makes it much more complex to setup and tune than other popular databases like MongoDB or PostgresSQL, which can run on a single server.

Exploring the Breadth First: Understanding Breadth-First Search

Aggregated on: 2023-10-01 17:01:54

In the vast realm of computer science and algorithms, there are numerous ways to solve problems and navigate through data structures. One such algorithmic technique that plays a fundamental role in graph traversal is known as breadth-first search (BFS). Breadth-first search is a simple yet powerful algorithm that systematically explores a graph or tree in a breadthward motion, covering all vertices at the same level before moving to the next level. The Concept Behind Breadth-First Search Breadth-first search operates on the principle of visiting neighboring vertices before exploring the deeper levels of the graph. It starts at a given source vertex and explores all of its adjacent vertices, then moves on to the next level of vertices until all reachable vertices have been visited. This process ensures that vertices closer to the source are visited before exploring those at deeper levels.

In today's rapidly evolving technology landscape, it's common for applications to migrate to the cloud to embrace the microservice architecture. While this architectural approach offers scalability, reusability, and adaptability, it also presents a unique challenge: effectively managing communication between these microservices. Successfully coordinating messages among these services is a fundamental aspect of their design. There are two popular methodologies available to tackle this challenge. The first, Service Orchestration, was discussed in my previous article. In this article, we will dig into the second methodology: Choreography. We aim to comprehensively understand the nuances, advantages, and disadvantages that the Choreography methodology brings. Problem Context To address the communication challenge, we introduced the concept of an orchestrator, a central authority tasked with coordinating and streamlining the flow of transactions across these autonomous microservices. But here's the question that looms large: Is the Orchestration Pattern a universal solution, or does its effectiveness vary depending on the scenario? Can a central orchestrator virtually manage all the business problems, or are there scenarios where a different approach besides being preferable is also essential?

Configuring RaptorX Multi-Level Caching With Presto

Aggregated on: 2023-09-29 22:31:54

RaptorX and Presto: Background and Context Meta introduced a multi-level cache at PrestoCon 2021, the open-source community conference for Presto. Code-named the “RaptorX Project,” it aims to make Presto 10x faster on Meta-scale petabyte workloads. This is a unique and very powerful feature only available in PrestoDB and not any other versions or forks of the Presto project. Presto is the open-source SQL query engine for data analytics and the data lakehouse. It enables you to scale independently and reduce costs. However, storage-compute disaggregation also brings new challenges for query latency as scanning huge amounts of data between the storage tier and the compute tier is going to be IO-bound over the network. As with any database, optimized I/O is a critical concern to Presto. When possible, the priority is to not perform any I/O at all. This means that memory utilization and caching structures are of utmost importance.

How To Get and Set PDF Form Fields in Java

Aggregated on: 2023-09-29 21:31:53

We’re now more than 30 years removed from the introduction of Portable Document Format (PDF) to the budding world of digital documents, and it’s safe to say the concept of a universally interoperable format hasn’t lost its appeal. To call PDF “popular” feels like a seismic understatement; it’s ubiquitous to an absurd degree. It’s not at all ridiculous to imagine that everyone in the world (with access to a computer) will interact with a document in PDF format at some point in their life, and it's likely that every modern business depends on PDF at some point as the export format for their various images, applications, contracts, invoices, and more. One of the major business advantages PDF offers (and has offered since 1996 — albeit under much different circumstances) is the ability to create and share forms that can be filled out digitally. As is the case now with most digitized processes, the manual counterpart to this process — i.e., printing forms, filling them out manually, and either scanning them or storing them for digital or physical archival — has fully evolved into an excruciating exercise in patience knowing that a purely digital version of that experience exists.

Micro Frontends for Quarkus Microservices

Aggregated on: 2023-09-29 21:16:53

Coined quite recently, the term Micro Frontend designates for a GUI (Graphical User Interface) what the one Microservice designates for classical services, i.e., the decomposition process of the different application's parts and components. More importantly, it not only applies to GUIs in general but to a more specific category of GUIs named SPA (Single Page Application). This is important because if there existed several techniques aiming at separating the different parts and components of a web application in general when it comes to SPAs, the story would become a bit more difficult. As a matter of fact, separating the different parts and components of a general web application often means separating its different pages. This process becomes more tricky for SPAs, as it concerns the separation of the different visual fragments of the application's single page. This requires a finer granularity and a more intimate orchestration of the content elements. The Micro Frontend concept adds more complexity to the web applications development field, which is already fairly complex by itself. The SPA model, as well as the emergence of the so-called JavaScript or TypeScript-based web application platforms and frameworks, brought to the picture a high degree of intricacy, requiring developers to have a vast amount of background knowledge, from HTML and CSS to advanced aspects of Angular, React, Node, Vue, and jQuery. In the Java world, a new category of software developers has come to light: the fullstack developers who not only need to deal with the grief of mastering Java, be it standard or enterprise, and all its underlying sub-technologies like Servlet, REST, CDI, JPA, JMS and many others, currently placed under the auspices of Jakarta EE, but who, increasingly, is required to master things like WebPack, SystemJS, Bower, Gulp and others Yeoman. Not to mention any more Spring, Quarkus, Micronaut, or Helidon.

Navigating the Cloud Conundrum: Open Source and Community vs. Enterprise Solutions

Aggregated on: 2023-09-28 22:01:53

Businesses find themselves at a pivotal crossroads when deciding on cloud computing options. Open-source and community-driven solutions offer one avenue, while enterprise solutions present another. With a myriad of considerations at play, it's easy to feel overwhelmed. This guide seeks to illuminate the path, providing clear distinctions to help you tailor your cloud infrastructure decision-making process. License Types and Considerations We begin by untangling the intricacies of licensing: Open Source Licenses: Examples include the GNU General Public License (GPL), MIT, or Apache License. They don't just permit usage; they often encourage community contributions. These licenses promote transparency and foster innovation, setting the stage for a global community of users and developers to collaborate. Proprietary Licenses: Here, users are essentially leasing software. They're granted permission to use, but there's no peeking behind the curtain, and redistribution is typically off the table. These licenses offer organizations a sense of exclusivity and often come with robust support. Questions To Reflect Upon Do you value the collaborative ethos and transparency of open source? Or do you seek the exclusivity and robust support accompanying proprietary licenses? How adept is your team at understanding and managing licensing intricacies? Development Considerations Let's explore the evolutionary journey of these solutions. Open Source Software Development Pros Collaborative evolution: Platforms like Kubernetes demonstrate that when minds from around the world converge, there's unparalleled innovation. This collective spirit can lead to features and solutions that are driven by real-world use cases. Rapid issue mitigation: Community-backed solutions mean many eyes are on the code. When platforms like Linux face issues, a global community rallies to patch them, often faster than conventional support channels. Flexibility: With platforms like OpenStack, you're not boxed into a specific operational paradigm. Instead, you can mold the software, ensuring it aligns perfectly with your unique operational requirements. Cons Variable quality: While there are flagship open-source projects known for impeccable quality, there's also a sea of projects with varying quality standards. Due diligence becomes paramount. Maintenance overheads: While customization offers power, it also brings responsibility. Customized solutions might necessitate dedicated teams for maintenance, adding to operational overheads. Proprietary Software Development Pros Structured progression: Solutions like AWS offer a sense of predictability. With clear development roadmaps, businesses can plan for the future with confidence, anticipating new features and improvements. Industry-aligned offerings: Platforms such as Azure don't just offer tools; they offer solutions crafted for specific industry needs, ensuring tighter alignment with business goals. Cons Reduced responsiveness: Being large entities, these platforms sometimes lack the agility of their open-source counterparts, potentially leading to slower adaptability. Feedback limitations: Without a sprawling community, there's a risk of becoming insular. Some user needs or innovative ideas might slip through the cracks. Questions To Reflect Upon Do you yearn for the organic, flexible evolution of open-source? Or is the structured, industry-aligned progression of proprietary platforms more your speed? How important is quick responsiveness and community feedback to your business's cloud infrastructure endeavors? Costs, Support, and Integration Dissecting the financial and operational nuances. Open Source and Community Solutions Cost efficiency: Beyond the apparent cost savings, open-source solutions often allow businesses to allocate resources more flexibly. As costs aren't tied to rigid licensing structures, there's room to invest in areas like training or customization. Driven by community: Solutions like Kubernetes are more than just tools; they're ecosystems. Their evolution is steered by user needs, industry trends, and a collective drive to push boundaries. Potential integration hurdles: While open-source offers flexibility, it sometimes lacks the seamless integration seen in proprietary ecosystems. Bridging the gap might require added expertise and resources. Paid or Enterprise Solutions Consistent reliability: Companies like AWS and Azure are behemoths for a reason. They offer SLA-backed performance, meaning businesses can expect a certain level of uptime and reliability, integral for mission-critical applications. Seamless ecosystems: Platforms like Google Cloud Platform go beyond standalone services. They offer a tapestry of interconnected tools, ensuring that different aspects of a business's operations harmoniously coexist. Navigating abundance: While a vast array of features is a boon, it also presents a challenge. Businesses must sift through the plethora, ensuring they harness tools that align with their goals without getting overwhelmed. Questions To Reflect Upon In terms of costs, are you looking for upfront savings or long-term, predictable investment structures? Do you value community-driven innovation, or is the cohesive, interconnected ecosystem of proprietary solutions more appealing? Conclusion Navigating the cloud landscape requires a blend of introspection and forward-thinking. Consider hybrid solutions — perhaps AWS for core operations paired with Kubernetes for container orchestration? Such combinations might offer a harmonious blend of both worlds. Whether drawn to the community-driven dynamism of open source or the structured dependability of enterprise solutions, your choice should echo both current needs and future aspirations.

A New Era Has Come, and So Must Your Database Observability

Aggregated on: 2023-09-28 21:46:53

The World Has Changed, and We Need To Adapt The world has gone through a tremendous transformation in the last fifteen years. Cloud and microservices changed the world. Previously, our application was using one database; developers knew how it worked, and the deployment rarely happened. A single database administrator was capable of maintaining the database, optimizing the queries, and making sure things worked as expected. The database administrator could just step in and fix the performance issues we observed. Software engineers didn’t need to understand the database, and even if they owned it, it was just a single component of the system. Guaranteeing software quality was much easier because the deployment happened rarely, and things could be captured on time via automated tests. Fifteen years later, everything is different. Companies have hundreds of applications, each one with a dedicated database. Deployments happen every other hour, deployment pipelines work continuously, and keeping track of flowing changes is beyond one’s capabilities. The complexity of the software increased significantly. Applications don’t talk to databases directly but use complex libraries that generate and translate queries on the fly. Application monitoring is much harder because applications do not work in isolation, and each change may cause multiple other applications to fail. Reasoning about applications is now much harder. It’s not enough to just grab the logs to understand what happened. Things are scattered across various components, applications, queues, service buses, and databases.

The Stairway to Apache Kafka® Tiered Storage

Aggregated on: 2023-09-28 21:01:53

It started back during Current 2022 when I attended Satish Duggana's session, giving a technical overview of Tiered Storage, a feature of Apache Kafka® that allows the offloading of data to object storage in the cloud. It was an excellent presentation, providing a technical overview of what Tiered Storage hoped to achieve, and it inspired me so much that I whipped up my laptop and started implementing an S3 prototype plugin at the end of the talk. What Is Tiered Storage and Why Should You Be Interested? Tiered Storage is arguably one of the most sought-after features of Kafka 3.6, allowing Kafka’s core data to be stored in other locations, such as object storage, in addition to hard disks in a transparent manner, without any changes to Kafka’s producers or consumers. The Kafka brokers control whether the data is stored on local disks, fast but expensive and limited, or in alternative storage places, such as Amazon S3. When Tiered Storage is properly configured, it means you can have the best of both worlds: recent data is stored on local fast disks (as is currently), and older, less frequently accessed data can be stored elsewhere where it's cheaper and space requirements are less of a concern (sometimes unlimited!)

AWS Lambda vs. Fargate: The Battle of Cloud Giants

Aggregated on: 2023-09-28 20:01:53

Cloud computing services have become indispensable in today's digital world. They offer businesses the ability to scale operations, manage vast amounts of data, and deliver faster services to customers. As organizations continue to digitize, the demand for robust, secure, and efficient cloud computing services is set to increase exponentially. With the advent of serverless architectures and container services, the technology landscape has transformed dramatically. AWS (Amazon Web Services) has been a major player in this transformation with their extensive suite of cloud services. Two such services that have gained significant popularity are AWS Lambda and Fargate. Let's dive into the depths of these two services, comparing them on various fronts to understand their strengths, weaknesses, and, most importantly, which one is more suitable for your needs. Overview AWS Lambda is a serverless computing service that runs your code in response to events, automatically managing the computing resources for you. It scales automatically and only charges for the compute time you consume. On the other hand, AWS Fargate is a serverless compute engine for containers, enabling you to focus on designing and building your applications instead of managing the infrastructure that runs them.
