Exécuter mes applications Go de manière sans serveur - Partie 2

Dans cet article, je vais vous montrer comment exécuter vos applications Go sans serveur, en utilisant des services cloud et des outils de développement. Partie 2 de cette série de tutoriels !

## La première partie de cette série vous a présenté le AWS Lambda Go API Proxy et comment ses implémentations d’adaptateur spécifiques au cadre / package (pour gorilla / mux, echo et net / http) vous permettent d’exécuter des applications Go existantes en tant que fonctions AWS Lambda frontées par Amazon API Gateway.

Le premier volet de cette série vous a présenté le AWS Lambda Go API Proxy et comment ses implémentations adaptées au framework/package spécifique (pour gorilla/mux, echo et net/http) vous permettent d’exécuter des applications Go existantes en tant que fonctions AWS Lambda frontées par Amazon API Gateway. Si vous ne l’avez pas encore fait, je vous encourage à y jeter un coup d’œil pour avoir une compréhension de base du AWS Lambda Go API Proxy.

Le AWS Lambda Go API Proxy prend également en charge Gin, qui est l’un des frameworks web Go les plus populaires ! Ce billet de blog suivant démontrera comment prendre un service de raccourcissement d’URL existant écrit à l’aide du framework Gin et le faire fonctionner en tant que fonction AWS Lambda sans serveur. Au lieu d’utiliser AWS SAM, nous allons changer un peu les choses et utiliser le AWS CDK pour déployer la solution.

Pour cela, nous allons créer une base de données DynamoDB pour stocker les URL raccourcies et une fonction Lambda pour gérer les requêtes entrantes. La fonction Lambda sera appelée par Amazon API Gateway et répondra aux requêtes GET et POST. La fonction Lambda utilisera la base de données DynamoDB pour stocker et récupérer les URL raccourcies. Une fois la base de données configurée et la fonction Lambda créée, nous allons utiliser le AWS CDK pour déployer le tout sur AWS.

Step Functions, the serverless finite state machine service from AWS. With DynamoDB, Lambda, and API Gateway, it forms the core of serverless AWS services. If you have tasks with multiple steps and you want to ensure they will get executed in the proper order, Step Functions is your service of choice.

It offers direct integrations with many AWS services, so you don’t need to use Lambda Functions as glue. This can improve the performance of your state machine and lower its costs.

From intrusion detection to threat analysis to endpoint security, the effectiveness of cybersecurity efforts often boils down to how much data can be processed in real-time with the most advanced algorithms and models.

Many factors are obviously involved in stopping cybersecurity threats effectively. However, the databases responsible for processing the billions or trillions of events per day (from millions of endpoints) play a particularly crucial role. High throughput and low latency directly correlate with better insights as well as more threats discovered and mitigated in near real-time. Cybersecurity data-intensive systems are incredibly complex: many span 4+ data centers with database clusters exceeding 1000 nodes and petabytes of heterogeneous data under active management.

Dynamo accelerated the NoSQL revolution that’s driving the database industry.

Recently, Amazon announced PartiQL – A SQL-Compatible Query Language for their flagship NoSQL database Amazon DynamoDB. This has brought the NoSQL “re:evolution” full circle. It’s wonderful to see the collaborative research from UCSD and Couchbase enabling the industry to move forward.

For some time, products have been leaning towards NoSQL databases because of the number of advantages that they provide compared to Relational databases (RDBMS), especially in today’s distributed systemsThere is always a pressure of delivering things faster to make it live to end users. But does that mean relational databases won’t be able to compete with NoSQL databases, provided Relational Databases are still best-known for adhering to the ACID property?

Here, I am going to explore the possibilities from Relational Databases perspective and how they come a long way to compete with NoSQL Databases. I am going to compare two managed databases from AWS, DynamoDB and Aurora, to see if it’s really worth giving credit to one type of database over another.

  • Mulesoft 4: Continuous Delivery/Deployment With Maven by Ashok S — This article is a great example of what we want every tutorial to look like on DZone. The main aim of this article is to provide a standard mechanism to release project artifacts and deploy to Anypoint Platform, from the local machine or configure in continuous delivery pipelines.
  • Integration With Social Media Platforms Series (Part 1) by Sravan Lingam — This article helps you to build a RESTful API through MuleSoft that integrates with LinkedIn and shares a post on behalf of one’s personal account. I like this article because, in the age of social media, it’s so important for businesses to be connected and integrated!

  • What Is Big O Notation? by Huyen Pham — Aside from a silly name, this article is an example of an in-depth analysis on a little-spoken-about concept. In this article, take a look at a short guide to get to know Big O Notation and its usages.
  • Is Python the Future of Programming? by Shormisthsa Chatterjee — Where is programming going? This article attempts to answer this question in a well-rounded way. The author writes, "Python will be the language of the future. Testers will have to upgrade their skills and learn these languages to tame the AI and ML tools".

These are strange times. Cities are in lockdown, and few are venturing outside. Therefore, the increased use of on-demand logistics services, like online food delivery, doesn’t come as a surprise.

Most of these applications provide a near real-time tracking of the ETA once you place the order. Building a scalable, distributed, and real-time ETA prediction system is a tough task, but what if we could simplify its design? We’ll break our system into pieces such that each component is responsible for one primary job.

Hey guys, I hope you all are doing well. I am back with another article on custom docker instances for databases. In my last post, we saw how we could have our custom docker instance for MySQL. Similarly, in this post, we will see how we can do the same with DynamoDB, so let’s get started.

Just like the scenario in the previous article, I was working on a project with DynamoDB as the database due to its many features like scalability, cloud storage, etc. And I wanted to test some things and did not want to mess with the cloud instance, so I thought to make an instance of my own, so what to do?
