海外TECH	DEV Community	Use Cloud Formation Templates to spin up MySQL instances on RDS	https://dev.to/aveekd22/use-cloud-formation-templates-to-spin-up-mysql-instances-on-rds-17d7	Use Cloud Formation Templates to spin up MySQL instances on RDSIn this article I am going to discuss how to set up a MySQL instance on AWS RDS using Cloud Formation templates In my previous article  How to configure an Amazon RDS environment for MySQL I have provided a detailed walkthrough of how to set up a MySQL instance on Amazon You can use the AWS console to provide all the information required for setting up the instance and then use it However in this article we will discuss an automated way of achieving the same functionalities using Cloud Formation templates What is a CloudFormation template In order to start writing the templates we first need to understand what cloud formation is all about AWS offers Cloud Formation as a cloud service that enables AWS customers to write the desired state of any infrastructure as a code and then use it to deploy resources to AWS It allows us to create a resource or a group of resources by following simple configuration templates For example if you want to deploy a web application on an EC instance that will also use an RDS database you can simply combine both the resources into one stack and write the code for setting up the instances Once you run it will create both the EC and the RDS instance and also deploy your web application Figure CloudFormation Template on AWS ConsoleThe components of a cloud formation template are as follows A JSON or YAML file in which the resources will be defined as a templateA stack can be a combination of multiple resources that needed to be set up as a part of the application For e g EC and RDSA changeset can be used to view a list of operations to be performed by the stackA stack set also can be considered as a managed group of stacks that be reproduced or replicatedOut of the above we will mainly focus on the JSON YAML template and the stack in this article The templates support a wide range of resources on AWS To get an exhaustive list please follow this link Writing the JSON or YAML template fileOne of the main challenges that we face while writing a template for the first time is what contents should be included in it To ease that AWS provides a lot of template samples that can be easily found on the official documentation Once you find the template required to create a necessary resource you can use it to create your own template The template can either be created using JSON or YAML and converted from one to another as well On a personal note I prefer writing the templates using YAML as it helps me keep away from the curly braces and commas and keeps the document cleaner However you are free to choose any option between JSON and YAML For this exercise let us try to spin up a MySQL instance on RDS and we will write the code in YAML In order to set up a MySQL database using cloud formation we would need the following items Resource Name The name of the resource you are going to set up Resource Type The type of the resource Resource Properties The database name username and password to connect to The database Engine MySQL SQL Server PostgreSQL etc Storage Type The storage type to be used Public Accessibility Weather the database should have public access or not Allocated Memory The memory that should be allocated to the database instance AWS Region The region in which the instance is to be created Now that we have some points with us let us go ahead and start by writing the template file Figure The template file for creating MySQL instance on RDSAs you can see in the figure above the structure of the file is divided into two parts In the first part we have defined a few parameters that will be used by the resource definitions in the second part while creating the resources on AWS You can use the same script on your machine to create an instance on your AWS account Setting up the stack on the consoleNow that we have created our template for MySQL it s time we set it up to see if everything runs well Head over to the AWS console and search for Cloud Formation on the search bar Click on Create Stack and upload the template file from your local Click Next once done Figure Creating the stack from the templateOn the next page you will be asked to provide the parameters that were defined in the cloud formation template Go ahead and provide the necessary details and click Next Figure Stack Parameters providedReview the stack changes and parameters and click on Create Stack on the last page The stack creation will start It might take some time to create all the resources before they are available to use In the meantime you can click on the Reload button to check if all the events have been created successfully Figure Stack Creation in progressAs you can see on the timestamps it took me around minutes after which the resources were available and were also visible on the console Navigate to the Resources tab and click on the Physical ID of the resource This will take you to the RDS console Figure Stack Created Successfully Connecting the MySQL databaseOnce you are in the RDS console you can get the hostname for the database instance and use it to connect to the database Grab the endpoint from the console and use it to connect Figure MySQL instance details on RDSLet us now head over to MySQL Workbench and try connecting to the hostname with the credentials that we have provided earlier Use the hostname username and password to connect to the instance Figure Connecting to the MySQL instance using MySQL WorkbenchAs you can see in the figure above we have successfully connected to the database instance on RDS Let us now run some queries and see if it works Figure Executing scripts in the MySQL WorkbenchAs you can see in the figure above we have been able to connect to the database instance and execute queries With this you are able to write your own cloud formation template and spin up any other resources like the SQL Server or PostgreSQL database Removing the resourcesIf you are performing this as an exercise I would recommend removing the resources that we have created as it will incur some charges You can navigate to the RDS console and then select the instance and click on Delete to remove the resources permanently Figure Deleting the resources createdOnce the resources have been deleted successfully you can check in the console once again if there are any instances running just to avoid adding unnecessary billing costs ConclusionIn this article we have discussed in detail how to set up a MySQL database instance in an AWS RDS environment and automate it using the Cloud Formation template This way if setting up resources on the cloud is also known as infrastructure as code service where you can set up the entire infrastructure as code and then use it in various environments These templates can be used not only to deploy database instances but also other infrastructures within the AWS such as EC Lambda RedShift etc To learn more about the cloud formation templates you can view the sample templates available on the official website	2022-03-22 08:27:05

海外TECH	DEV Community	Engineering your startup idea	https://dev.to/varungujarathi9/engineering-your-startup-idea-3hi3	Engineering your startup ideaI have been a great fan of Software Engineering wherein things are built ground up but the sheer thought of building a product from a software perspective can be daunting for beginners I have been fooling around web development since early First it was plain JS then dynamic PHP and then gradually learning various frameworks libraries like React Node Flask Django Spring etc I have also worked on infra tools like cPanel AWS Kubernetes Docker and many others While I was in college the question of funding the websites was not an issue since the websites I built were developed for college activities and each of them had a budget As I started working on personal projects with advanced frameworks I realized that funding them matters especially when you are young and do not have the privilege of seed funding There are a few more things that I have understood from all these experiences until now Idea validationIf you currently have just one or two ideas to build around kick start one of them don t wait to validate these ideas Once you start building stuff and put your mind in value creation mode more ideas would pop up This seems like an intelligence privilege but believe me once you start working on an idea things start popping up Now if you do have multiple ideas to work on do a basic validation of the idea Talk to people around you ask them whether they think they have a use for your product in their lives Don t just directly ask them I am building XYZ Would you use it They would say Yes without giving it much thought The right question here would be to ask them whether they face the same problem the one that your product would solve Ask them what solution they think could solve this expect hyper realistic answers Now put your solution in front of them Of course everyone would be entitled to their opinion everyone is emotionally attached to their thoughts and everyone thinks that their way is better Now it is on you to decide what ideas you would incorporate in your solution Idea to POCOnce you have the design ready in your mind remember it may not be perfect you might not have figured out everything that s fine what is important is you kickoff start developing the solution in any language and framework that you are comfortable in You don t need to build it in Java just because Java is robust You don t need to build micro services a monolith app would do your job You don t need a Kubernetes cluster or highly secured network Understand that your job as a lone engineer is to build the solution first Once you build it then think of making it better Tools for quick bootAs I said early the aim is to quickly build a POC and it can be slow or have vulnerabilities no one is going to hack you at this point of time So to get the end to end solution up and running you can use Heroku to host the app ElephantSQL for PostgreSQL webhost for MySQL Mongo Atlas for MongoDB etc All these platforms provide free services respectively A view on no codeNo code tools can help you quickly develop the solution Though in the long run it would never sustain and you wouldn t be able to build every feature on it Doing what is right First principle thinking is very important in every aspect of life You should have strong reasoning as to why you are using a certain technology to build something For example if the team has decided to have a website where they can put the basic information about the product or the idea the best solution here would be to build it within no time using WordPress or Wix Just because you like Angular don t invest your time in building the portfolio website using Angular It is one thing to learn new technology and another to build and deliver something Understand the risk and rewardsUnderstand the concept of trade off The trade off between the development speed of the engineers and the performance amp scalability of the application The trade off between using NoSQL amp SQL databases etc Everything has its pros and cons try to adapt the best out of each technology and deliver what is needed Understand the needs and accordingly pick the tools There is no point in cutting the cake with a sword A knife has its utility and a sword has its own Not all new tech is adaptableYour product doesn t need to be built using the latest cutting edge technologies Most of the technologies are built on C C amp Java and frameworks that most people would think are old But again it all boils down to the fundamentals of each and everything Spring is still used after years because its robustness and other characteristics Disclaimer Node Go Python have their fair share and are not evil at all Read this blog by Kailash Nadh Remember to start small and grow bigThe utmost important thing is to Start Start from wherever you want write a simple code create a minimal web page

海外TECH	Engadget	New SEC rules require would companies to disclose climate goals and emissions	https://www.engadget.com/new-sec-rules-require-would-companies-to-disclose-emissions-and-climate-goals-084634208.html?src=rss	New SEC rules require would companies to disclose climate goals and emissionsPublic companies would be required to disclose greenhouse gas emissions they produce under new rules proposed by the US Securities and Exchange Commission The move is part of the Biden government s push to identify climate risks and cut emissions as much as percent by The SEC s three Democratic commissioners voted to approve the proposal while Republican commissioner Hester M Peirce voted against it quot I am pleased to support today s proposal because if adopted it would provide investors with consistent comparable and decision useful information for making their investment decisions and it would provide consistent and clear reporting obligations for issuers quot said SEC Chair Gary Gensler Under the new rule companies would need to explain how climate risks would affect their operations and strategies They d be required to share the emissions they generate and larger companies would need to have those numbers confirmed by independent consulting firms They d also need to disclose indirect emissions generated by supplies and customers if those are quot material quot to their climate goals nbsp The SEC proposed rule changes that would require registrants to include certain climate related disclosures in their registration statements and periodic reports ーU S Securities and Exchange Commission SECGov March In addition any companies that have made public promises to reduce their carbon footprint would need to explain how they plan to meet those goals That includes the use of carbon offsets like planting trees which have been criticized as being a poor substitute for actually slashing emissions as Greenpeace said in a recent report nbsp The SEC already allows for voluntary emissions guidance but the new rules would make it mandatory Many companies like Ford already share emissions date from factory production as well as vehicle fuel usage However quot there are lots of companies that won t do it unless it s mandatory quot task force chief Mary Schapiro told The Washington Post ahead of the report s release nbsp After the proposed rule is published on the SEC s website the public will have days to comment The final rule will likely head to a vote in several months and would be phased in over several years The ruling will likely be challenged in court by Republicans in states like West Virginia along with business groups on the grounds that climate change is not a material issue for investors in the near future nbsp However experts have warned that time is of the essence The Intergovernmental Panel on Climate Change IPCC recently issued a report stating that many of the impacts of global warming are quot irreversible quot and that there s only a brief window of time to avoid the worst UN Secretary General Antonio Guterres called it a quot damning indictment of failed climate leadership quot nbsp	2022-03-22 08:46:34
