海外TECH	DEV Community	How to start your open source journey with UNICEF?	https://dev.to/rachita_saha/how-to-start-your-open-source-journey-with-unicef-2hd	How to start your open source journey with UNICEF If you are looking for ways to start your open source journey and would like to use your technical skills to contribute towards achieving sustainable development here s an article you might find useful All you need to contribute to UNICEF s open source projects are working knowledge of Git GitHub web development and enough determination to make that first pull request The feeling of fulfillment you will receive when the first PR gets merged will keep you motivated to continue learning and contributing What are Digital Public Goods In alignment with the UN Secretary General s Roadmap for Digital Cooperation Digital Public Goods DPGs are defined as “open source software open data open AI models open standards and open content that adhere to privacy and other applicable best practices do no harm and are of high relevance for attaining the UN s Sustainable Development Goals SDGs Many types of digital technologies data and content from open data to apps visualization tools to educational curricula could accelerate the achievement of the SDGs However it is only if they are freely and openly available with minimal restrictions on how they can be distributed adapted and reused that we can think of them as “digital public goods What is the Digital Public Goods Alliance UNICEF along with the Governments of Norway and Sierra Leone and the India based think tank iSPIRT have jointly established the Digital Public Goods Alliance DPGA a multi stakeholder initiative to accelerate the attainment of the SDGs in low and middle income countries by facilitating the discovery development use of and investment in digital public goods The DPGA is an effort to convene a network of partners from different sectors that will contribute to the identification support scale up and use of software data and algorithms that can advance humanity ‍How can you contribute There are a few projects of the DPGA that you can contribute to but instead of jumping straight into the code base I would recommend the following approach to best understand the goals of the DPGA and make meaningful contributions Nominate a DPGThis process involves identifying open source solutions that contribute to an equitable world and adhere to the DPG Standard The unicef publicgoods candidates repository is used to manage the process of adding nominees for consideration as Digital Global Public Goods While you can easily make a contribution through the submission form I would strongly suggest opening a pull request making sure it passes the CI build and getting it merged The instructions for nominating DPGs through both methods are mentioned very clearly in the contribution guidelines Go ahead and make that first contribution Validate DPG submissionsYou can participate by reviewing open source projects against the Digital Public Goods Standard with the ultimate goal of determining if a project qualifies as a DPG This community sourcing exercise will give you the opportunity to delve into some of the largest up and coming open source projects understand their licenses and documentation and how they re designing for best practices standards privacy and more By participating you ll get a better understanding of open projects that are making a difference in the world particularly those that are advancing practical solutions to help achieve the SDGs You will also join a growing number of innovators working on Technology for Development TD Solve issues in the various repositoriesThe next step is to take a look at the various issues listed on UNICEF s GitHub repositories When you find an issue that interests you drop a comment asking to be assigned to it If you don t understand the issue entirely ask for help through comments Below is a list of the various UNICEF repositories you can contribute to Before diving into the solutions I would strongly recommend you to go through the documentation thoroughly and set up the project on your local machine Then move to the Issues tab on any repository find an issue with the tag good first issue and try solving it If you don t find any issues that interest you you can create a new one You just need to take a look at the code and try to identify bugs or make suggestions to improve the content design documentation etc The large codebase might appear intimidating at first but it is not as hard as it appears I was a beginner too when I started contributing and I understand that it takes some effort to navigate through it all but the satisfaction of seeing your changes merged into the repository ultimately contributing towards the good of the public is absolutely worth the effort ConclusionOpen source represents an opportunity to fundamentally alter power balances in international development UNICEF aims to harness that power through the cooperation of its many contributors and this is your chance to be one Being an open source contributor was one of the best learning experiences for me and I encourage everyone to give it a try I hope this blog helped you in some way If you have any other questions related to the process feel free to drop a comment below Best of luck and happy

海外TECH	DEV Community	Cloud cost reporting alone isn’t going to cut your AWS bill	https://dev.to/castai/cloud-cost-reporting-alone-isn-t-going-to-cut-your-aws-bill-2ipa	Cloud cost reporting alone isn t going to cut your AWS billAs containerization rises in popularity traditional cost optimization methods like monitoring and reporting are put to the test Getting a detailed report of your cloud spend is just one side of the coin The other and arguably more important one is doing something about these findings Keep on reading to find out why adding automated optimization techniques to the mix makes all the difference and generates some serious savings Cloud cost reporting is a must have there s no doubt about itTeams usually use Kubernetes in dynamic and multi tenant environments Since increasing resources is so easy losing control over cloud spend is even easier If left unchecked a missed bug or architecture oversight might easily snowball into a massive expense Consider this story One of Adobe s development teams once burned per day because of a computing job left running on Azure Before someone discovered it and pulled the plug the bill snowballed to more than half a million dollars One simple alert would be enough to prevent this That s why users need a solid cost reporting tool that brings them cost visibility in detailed reports and sends alerts when certain parts of the infrastructure go beyond the set thresholds  Cost reporting is incredibly important but like I said it s just one side of the cost optimization coin But cost reporting alone doesn t cut the chaseYou need more than cost reports to make a real difference in your setup After all what cost monitoring and reporting tools give you are static recommendations that require a human to implement them If you have a small environment a human engineer can make it work But think about the scale of a mid sized company or enterprise Applying all the recommendations manually and on a regular basis translates into time which translates into cost not to mention all the lost optimization opportunities for sudden traffic spikes and such What you need is to add automated cost optimization to the mix If you re wondering how the combination of Kubernetes cost reporting and optimization works in practice here s a case study that shows it step by step How automated cost optimization helped reduce Amazon EKS costs in minutesTL DRI provisioned an e commerce app see it here on an EKS cluster with m nodes vCPU GiB on the Amazon EKS platform Then I deployed an AI engine to go through my application and suggest some optimizations I got some pretty interesting recommendations in the Savings Report so I activated the automated optimization feature Here are the results Initial cluster cost month Within minutes after turning the automation on the cluster cost got down to a reduction by eliminating nodes And minutes later the solution added Spot Instances which made the cluster costs go down to per month a reduction Here s a more detailed take on this case studyStep Generating the Savings ReportAfter creating and deploying my EKS cluster I connected it to CAST AI by creating a free account and selecting Connect your cluster I then copied and ran the script successfully in my terminal The CAST AI agent analyzed my EKS cluster in read only mode and generated this Savings Report As it turns out if I switched my m large to ca large I could slash my bill by almost  And I could get even higher savings if I decided to use Spot Instances Step Activating the cost optimizationTurning automated optimization on made a lot of sense so I had to grab my AWS access key ID and Secret access key and add both to the platform  To get the access keys I had to run this script Step Enabling cost policiesTo achieve maximum cost savings I turned on all the policies available in CAST AI CPU Policy I used this policy to set the maximum budget of CPUs Node autoscaler Whenever I get unscheduled pods CAST AI will start looking for a place to run them starting with Spot Instances if they re Spot Instance friendly or On Demand instances Node Deletion Evictor Evictor is a background process that continuously reduces the cluster to the minimum number of nodes by bin packing pods Once a node becomes empty it s instantly deleted  Step Running EvictorThis is what the last policy and Evictor tool look like in action One node marked in red is identified as a good candidate for eviction Evictor automatically moves pods to other nodes for “bin packing Once the node becomes empty it s deleted from the cluster Evictor returns to step and keeps on looking for other nodes that could be deleted to cut costs After about minutes Evictor deleted nodes and left just nodes running CPUs were at a much healthier rate The cost of my cluster is now per month so of the initial cost per month Step Moving workloads to new optimized nodesThis is a more advanced and optional step where CAST AI actively replaced my current nodes with more optimized ones for example Spot Instances To do that CAST AI cordons the cluster drains nodes and then replaces them with more optimized nodes So my nodes were cordoned The first two nodes were drained and the AI engine selected the best instance type for these nodes Here s what I saw in my CAST AI dashboard As you can see my cluster is now running on nodes that cost me per month It s hard to believe that I initially got a monthly EKS bill of Running clusters on Amazon EKS Give automated optimization a tryRun the free CAST AI Savings Report to check how much you could potentially save It also gives you actionable steps to reduce the bill that other tools ask you to pay for And when you re ready turn automated cost optimization on to see how your cloud bill shrinks with every minute	2021-07-22 16:12:27
