Learn How To Use DynamoDB Streams With AWS Lambda and Go

Aggregated on: Thu Jul 21 2022 16:06:34 GMT+0000 (Coordinated Universal Time)

This blog post will help you get quickly started with DynamoDB Streams and AWS Lambda using Go. It will cover how to deploy the entire solution using AWS CDK. The use case presented here is pretty simple. There are a couple of DynamoDB tables and the goal is to capture the data in one of those tables (also referred to as the source table) and replicate them to another table (also referred to as the target table) so that it can serve different queries. To demonstrate an end-to-end flow, there is also an Amazon API Gateway that front ends a Lambda function which persists data in the source DynamoDB table. Changes in this table will trigger another Lambda function (thanks to DynamoDB Streams) which will finally replicate the data into the target table.

Invoking an AWS Lambda Function During a CDK Deployment

Aggregated on: Thu Jul 21 2022 02:06:34 GMT+0000 (Coordinated Universal Time)

In general, AWS Lambda functions are triggered by some sort of event. Most common use cases are an event from EventBridge, SQS, or an event created by a call to API Gateway in case you have a REST/HTTP API based on an AWS Lambda function. However, the other day I was looking for an option to execute my Lambda function immediately after it was created and/or updated while deploying my Infrastructure as Code with AWS CDK. I wanted it to work without manually executing a CLI command or calling an HTTP endpoint. It needed to be based on the CDK / CloudFormation deployment. A couple of use cases we had was triggering an import process or running a liquibase/ flyway script to populate a database. Looking for Options While researching options, I initially looked for a method on the Function CDK Construct. I wondered if had specific lifecycle methods, but that did not seem the case. Secondly, I started looking at an EventBridge rule that could listen to AWS CloudFormation events, but it seems there are almost no events coming out of CloudFormation into EventBridge.

Developing a Multi-Cluster-Friendly Kubernetes Operator

Aggregated on: Thu Jul 21 2022 01:36:34 GMT+0000 (Coordinated Universal Time)

Cassandra is a highly scalable database with an architecture that makes it well suited for multi-region workloads. As companies are standardizing on Kubernetes, they often want their clusters to span across multiple zones within a single region. However, multi-region Kubernetes clusters have serious technical challenges to overcome to be used in production. The challenge of handling stateful workloads on a multi-cluster Kubernetes setup, and more specifically with Kubernetes operators, was heavily discussed at KubeCon EU 2022. In this presentation, DataStax Software Engineer John Sanda introduces K8ssandra Operator, which has been designed specifically to address the issue of running Cassandra on a Kubernetes multi-cluster deployment. John discusses how it was designed, how to reconcile objects across multiple clusters, how to manage secrets, pitfalls to avoid, and testing strategies. All of this knowledge can be ported to build other multi-cluster-friendly Kubernetes operators.

How to Host a Static Website on AWS With S3, CloudFront, Route53 and Terraform

Aggregated on: Wed Jul 20 2022 21:06:33 GMT+0000 (Coordinated Universal Time)

Hosting a website on AWS using Cloudfront, S3 and Route53 is a popular solution for Amazon web hosting. It typically costs $3 a month outside the generous free tier and $0.50 within the free tier. Terraform can automate the deployment of this finicky architecture, making it much easier to deploy, manage and automatically upload website content. We will use an open-source Terraform module to deploy a secure, scalable, and performant website on AWS based on Route 53, CloudFront, and S3. Architecture The vast majority of Terraform tutorials I see covering similar topics all focus on recreating an identical architecture from stack utilizing resources which is simply a waste of time and effort. Existing tutorials and modules generally follow the architecture shown below, which is based on the AWS tutorials. Configuring a static website on Amazon S3 and Speeding up your website with Amazon CloudFront. Since they are based on tutorials, the following flaws remain:

5 Options for Deploying Microservices

Aggregated on: Wed Jul 20 2022 20:06:33 GMT+0000 (Coordinated Universal Time)

Microservices are the most scalable way of developing software. But that means nothing unless we choose the right way to run them: processes or containers? Run on my servers or use the cloud? Do I need Kubernetes? When it comes to microservice architecture, there is such an abundance of options, and it is hard to know which is best. As we’ll see, the perfect place to host a microservice application is largely determined by its size and scaling requirements. So, let’s go over the 5 main ways we can deploy microservices.

Should You Invest in a Digital Transformation Office?

Aggregated on: Wed Jul 20 2022 18:36:34 GMT+0000 (Coordinated Universal Time)

Undertaking a digital transformation journey is easier said than done. Efforts to transform an organization often face significant challenges, including integration of legacy platforms with modern technology stacks, the skill sets required for implementation, and an organizational structure that can communicate and embrace change. According to a 2020 study by the Boston Group, 72% of digital transformations fail, falling short of their objectives, and are often met with radical consequences after. With so much at stake when it comes to transforming an organization, Adecco Group’s Sabine Laute suggests that a dedicated transformation office could be a viable solution.

Working With Geospatial Data in Redis

Aggregated on: Wed Jul 20 2022 18:36:34 GMT+0000 (Coordinated Universal Time)

Working with geospatial data is notoriously difficult because latitude and longitude are floating point numbers and should be very precise. In addition, it would seem that latitude and longitude can be represented as a grid, but in fact, they can't, simply because Earth is not flat, and mathematics is a complex science. For example, to determine the distance of a great circle between two points on a sphere, based on their latitude and longitude, the haversine formula is used, which looks like this:

Writing Your Own Service Discovery Client for Apache APISIX

Aggregated on: Wed Jul 20 2022 18:36:34 GMT+0000 (Coordinated Universal Time)

In general, API Gateways - and in particular, Apache APISIX - provide a single entry point into one's information system. This architecture allows for managing load balancing and failover over similar nodes. For example, here's how you can create a route balanced over two nodes in Apache APISIX: Shell curl http://localhost:9080/apisix/admin/routes/1 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -i -d '{ "uri": "/*", "upstream": { "type": "roundrobin", "nodes": { "192.168.0.1:80": 1, # 1 "192.168.0.2:80": 1 # 1 } } }'

Why a Cloud-Native Database Must Run on K8s

Aggregated on: Wed Jul 20 2022 17:21:34 GMT+0000 (Coordinated Universal Time)

We’ve been talking about migrating workloads to the cloud for a long time, but a look at the application portfolios of many IT organizations demonstrates that there’s still a lot of work to be done. In many cases, challenges with persisting and moving data in clouds continue to be the key limiting factor slowing cloud adoption, despite the fact that databases in the cloud have been available for years. For this reason, there has been a surge of recent interest in a data infrastructure that is designed to take maximum advantage of the benefits that cloud computing provides. A cloud-native database is one that achieves the goals of scalability, elasticity, resiliency, observability, and automation; the K8ssandra project is a great example. It packages Apache Cassandra and supporting tools into a production-ready Kubernetes deployment.

Context It could be a basic "Hello, World!" application or a complex banking solution like Stripe, but developing an application is a fascinating process. This process typically includes extensive testing and quality assurance to ensure that not only the requirements are met but also that the application is reliable enough for users to consume. While this procedure is thorough, faults and errors do occur over time as users interact with the program, and the application must be quickly troubleshot to remedy these bugs or mistakes.

Designing a Multi-Language Database

From the world’s largest companies to smaller enterprises, sustainable practices and environmental stewardship are core to a successful business strategy. Once seen as a forward-thinking competitive advantage, sustainability has evolved into a necessity in the global economy and a key consideration for enterprises. Since global internet usage accounts for 3.7% of all global emissions, companies are looking for energy-conscious solutions that don't affect performance or scalability. A recent survey found that 80% of enterprises strongly consider environmental impacts when choosing larger internet providers. To meet these enterprise demands, many large network providers are moving to renewable network solutions.

Writing Indexes in Java by Using Right Collection

Aggregated on: Tue Jul 19 2022 20:51:33 GMT+0000 (Coordinated Universal Time)

What Index Is and How To Use It in Java An Index is a structure that facilitates search in your data. Is a pretty general term and doesn't belong to some language or database. In order to explain it let's create a way to search users for specific criteria like name, id, birth date, etc. Quickly Searching Among Millions of User Entries Let's assume that we have 1 million users. As a requirement, we have to expose API to search users by specific criteria. Obviously, simple iteration will take too much time. So let's sort this problem using indexes (or simply saying by pre-generating some data that accelerate lookup during API calls). So first place let's define our User class and Search interface:

The James Webb Space Telescope is finally up and running, bringing back images of galaxies at mind-boggling distances from Earth. Hubble’s successor was three decades in the making and cost more than ten billion dollars. The code executed on hardware a million miles from Earth must have been written with superior attention to detail and quality. Well, I assume. The cost to get the reliability you need for those top echelons of mission-critical software is highly non-linear. Squeezing out a hundredth percentage point, to go from 99.99% to 99.999% uptime, is expensive. It must be worth the effort. So, we adjust quality needs based on risk. How much will we suffer if the software reveals crucial bugs after deployment? How likely is this and how do we mitigate those odds? How fast can we track down and repair mistakes? For the Webb telescope, the answer is obvious: the reputational damage alone would be devastating. If serious bugs ruin a project because they can’t be quickly rectified, then a mega investment in first-time-right is justified.

How to Use MQTT in Python (Paho)

Aggregated on: Tue Jul 19 2022 17:51:33 GMT+0000 (Coordinated Universal Time)

Python is an interpreted, high-level, general-purpose programming language. Created by Guido van Rossum and first released in 1991, Python's design philosophy emphasizes code readability with its notable use of significant whitespace. Its language constructs and object-oriented approach aim to help programmers write clear, logical code for small and large-scale projects.1 MQTT is a kind of lightweight IoT messaging protocol based on the publish/subscribe model, which can provide real-time and reliable messaging service for IoT devices, only using very little code and bandwidth. It is suitable for devices with limited hardware resources and a network environment with limited bandwidth. Therefore, MQTT protocol is widely used in IoT, mobile internet, IoV, electricity power, and other industries.

Automated Functional Testing: A Step-by-Step Guide

Aggregated on: Tue Jul 19 2022 17:21:33 GMT+0000 (Coordinated Universal Time)

Every application (desktop, web, or mobile) needs to be tested before releasing to the market. Functional testing is considered the most important type of testing because, first of all, an application must do WHAT it is required to do. Functional testing verifies that each software function operates in conformance with the requirements specifications. If an application doesn’t meet its functional requirements, it might not survive for long.

In my opinion, the deployment of any application should be as automated as possible to avoid errors due to manual mistakes. This is no different with a mule esb application. If you are using the enterprise edition of the mule esb you also have the ability to make use of the mule management console (MMC). This instrument makes the governance of the deployment of your mule applications into different environments easier, and therefore, the whole deployment cycle less error-prone.

A View of Different Pages If you are a Windows 7 phone owner, you may have noticed that your phone has different pages that you can engage with. This is intentional, of course, and allows for users of this phone to get access to exactly the information that they want at any time. Developers look at this as somewhat of a challenge. They need to figure out how they can keep certain bits of information from page to page while transferring other bits, and it is all about what they think their users will need to see from page to page.

Configuring Spring Boot Application Properties in Containerized Environment

Aggregated on: Tue Jul 19 2022 16:51:33 GMT+0000 (Coordinated Universal Time)

Until a few years ago, monolithic applications were common. With numerous functions knitted into the fabric of the codebase and interdependencies running through them, it was difficult — or even impossible — to work on individual functions in isolation. To add to the complexity, managing multiple environment-specific configuration was a nightmare. That is when Spring introduced the interesting feature of creation of multiple environment profiles with application.properties /application.yml. Creating a bunch of application-[profile].properties files like application-local.yml, application-test.yml, application-dev.yml was very common in those days to create different environment-specific configurations. Fast Forward to Today As the technology progressed, soon organizations started adapting modern ways of not only developing the application, but also deploying them. With introduction of microservices architecture and containerization technologies like Kubernetes and Docker, there came the inherent need of managing and deploying it in a cleaner way.

What Is Text Classification?

Aggregated on: Tue Jul 19 2022 16:21:33 GMT+0000 (Coordinated Universal Time)

What Is Text Classification? Text Classification is the process of categorizing text into one or more different classes to organize, structure, and filter into any parameter. For example, text classification is used in legal documents, medical studies, and files, or as simple as product reviews. Data is more important than ever; companies are spending fortunes trying to extract as many insights as possible. With text/document data being much more abundant than other data types, new methods of utilizing them are imperative. Since data is inherently unstructured and extremely plentiful, organizing data to understand it in digestible ways can drastically improve its value. Using Text Classification with Machine Learning can automatically structure relevant text in a faster and more cost-effective way.

10 Threats to an Open API Ecosystem

Aggregated on: Tue Jul 19 2022 14:51:33 GMT+0000 (Coordinated Universal Time)

Despite tight economic situations worldwide, the API economy continues to grow. For most industries, APIs facilitate instantaneous transactions across almost any application or service, expediting the flow of goods and services. A recent report from F5 described the proliferation of APIs in this way: “If data is the new oil, then APIs will become the new plastic.” Open APIs (or public APIs) provide many opportunities and competitive advantages. Companies can leverage open APIs to reshape their supply and delivery chains. Businesses can tap into a wide pool of developer talent and an ever-growing repository of software resources. Furthermore, companies can release their commercially developed APIs as open APIs later. By doing so, they can attract new customers, increase brand loyalty, and enhance their marketplace profile.

For any production environment, having a proper logging and monitoring system is vital. This is down to the fact that downtime can lead to unwanted bottlenecks in such an environment and even loss of business reputation and revenue. As a result, most organizations that utilize DevOps principles and tools require a logging system to cover the shortcomings of Prometheus, which is an efficient production system monitoring tool but lacks logging capabilities. Grafana Loki is one of the tools that help companies maintain a centralized logging system. The importance of having a centralized logging system in a production environment is that it allows you to address issues such as downtime and identify potential issues that need resolution. Loki started at Grafana Labs in 2018 and was announced at the KubeCon in Seattle in December 2018. In June 2019, the first beta version 0.1.0 was released.

If you frequently find yourself immersed into the MySQL world, there's probably no need to explain to you what SQL queries are and what they do. Chances are, you know them like your five fingers. SELECT queries allow us to read data, INSERT queries allow us to insert data into a given database, UPDATE queries allow us to update data for certain rows or for the entire table if we wish, DELETE queries let us delete records from a table, etc. If you've ever dug deeper into the world of MySQL though, you must know that there is one more query that is very important for both database administrators and developers — that query is ALTER TABLE. What Is ALTER TABLE? Simply put, ALTER TABLE is a query in MySQL that allows us to modify (or ALTER) the structure of a table. The things that ALTER TABLE can do are numerous — ALTER TABLE can be used to change names of tables or columns, or add or modify columns as well. On its end though, ALTER TABLE is mostly used when indexes are involved — when developers need to add indexes, they change the structure of their tables, and that's where ALTER TABLE comes into play once again.

Write Your Kubernetes Infrastructure as Go Code — Cdk8s-Plus in Action!

Aggregated on: Mon Jul 18 2022 21:51:32 GMT+0000 (Coordinated Universal Time)

One of my previous blog posts covered how to get started with cdk8s (Cloud Development Kit for Kubernetes), which is an open-source framework (part of CNCF) using which you can define your Kubernetes applications using regular programming languages (instead of yaml). You were able to set up a simple nginx Deployment and accessed it via a Service - all this was done using Go, which was then converted to yaml (using cdk8s synth) and submitted to the cluster using kubectl. This was a good start. However, since the core cdk8s library is pretty low-level (for a good reason!) the code involved a lot of boilerplate (you can refer to the code here).

The upheaval suffered by manufacturers since the onset of the COVID-19 pandemic is forcing companies to rethink their processes. It’s not surprising that Six Sigma thinkers, as process improvement experts, are high on the go-to list for help. But for Six Sigma experts, it’s also time to rethink.

Questions Developers Should Consider Asking Potential Employers

Aggregated on: Mon Jul 18 2022 18:21:32 GMT+0000 (Coordinated Universal Time)

During the whole recruitment process, we are asked a lot of questions to prove our skills as software engineers. This is understandable, as each company wants to get the best employee to meet their — more or less sane — criteria. It is equally understandable that we, as engineers, also want to work for the best companies out there. The “best” company means something different to each one of us, but no matter our criteria, we still need to work out a way to filter out the right companies or at least cross out the wrong ones.

This article is adapted from my new book, Modern Computer Architecture and Organization. Second Edition, published by Packt Publishing. For more detail on the mathematics and economics of self-driving vehicle architectures, including details on implementing the CNN image recognition architecture discussed in this article using TensorFlow, please see Chapter 16 of the book. Overview of Self-Driving Vehicles Several major motor vehicle manufacturers and technology companies are actively pursuing the development and sale of fully self-driving, or autonomous, motor vehicles. The utopian vision of safe, entirely self-driving vehicles beckons us to a future in which commuters are free to relax, read, or even sleep while in transit and the likelihood of being involved in a serious traffic accident is drastically reduced from the hazardous situation of today.
