Written by Hyojung Yoon Hello! Today we're going to talk about CDNs. In our ever-evolving digital world, we all want a fast and reliable connection to internet content. Have you ever wondered how websites load quickly when you access them from the other side of the world? The answer lies in a technology called a CDN, or Content Delivery Network . In this article, we'll take a quick look at what a CDN is, how it works, and do a comparative analysis of the leading CDN solutions. So let's get started! What is a CDN? How CDN works Benefits of CDN Improve web page load times Reduce bandwidth usage and costs Increase content availability Respond to traffic spikes Increased security Comparison of CDN Services CloudFront Akamai Cloudflare Fastly Conclusion What is a CDN? A Contents Delivery Network(CDN) is a network of servers distributed around the world to deliver content to users quickly and securely. By delivering content from servers closer to the user, it speeds up delivery and significantly reduces latency. To make it easier for you to understand, let's compare a CDN to a courier delivery system. Think of the Internet as a giant courier delivery system for websites and content. Just like a courier system that sends packages from one place to another, a CDN helps deliver content (images, videos, text, etc.) to your computer or smartphone. When you order something online, it's usually shipped from a warehouse to your home. Similarly, a CDN stores content in multiple locations around the world (called servers) and delivers it to you from the closest server. This makes content load faster and provides a seamless online experience. How CDNs work Imagine you're accessing your favorite website on your smartphone or computer. If the website's servers are located far away, the webpage might take a while to load. This is where a content delivery network, or CDN, can help speed up the delivery of the content you're trying to access. A CDN is a network of interconnected servers that work together to distribute content, such as images, videos, or web pages, to users around the world. When a user requests content, the CDN identifies the servers closest to the user (also known as edge servers ) and delivers the content from those servers instead of the origin server. This greatly reduces the time it takes for the content to travel, making it faster and more efficient to deliver. To further optimize this process, CDNs utilize caching , which stores copies of content on multiple servers across the network. By utilizing caching, when a user requests content, the requested content is readily available on the closest server. This allows CDNs to reduce latency-the time it takes for content to be delivered from the origin server to the user. As a result, CDNs play an important role in improving website and application performance, providing a faster, smoother internet experience for you and your fellow users. Benefits of CDN 1. Improve web page load times CDNs use CDN servers close to your users to serve content, which results in faster page load times. If your page load times are too slow, users might bounce, and your site traffic might decrease. A CDN reduces this bounce rate and increases the amount of time users spend on your site, so more users stay longer. 2. Reduce bandwidth usage and costs Web hosts charge based on the data transferred from their servers. By storing a copy of the content closer to the user, a CDN reduces the amount of data transferred from the original server. By doing so, the CDN reduces the amount of data that the original server has to serve, reducing bandwidth usage and costs. 3. Increase content availability Too many visitors at once or a hardware failure can cause your website to crash. Because CDNs are decentralized, they can handle more traffic and withstand hardware failures. Plus, if one or more CDN services go offline, other operational servers can replace them to ensure that your service is not interrupted. 4. Respond to traffic spikes A distributed denial of service (DDoS) attack attempts to bring down a server by sending large amounts of fake traffic to a website. CDNs can handle spikes in traffic by reducing the impact on the origin server through methods such as distributed processing, which spreads the load across multiple servers, and distinguishing between normal and abnormal requests. 5. Increased security CDNs can increase security by mitigating distributed denial of service (DDoS) attacks, improving secure authentication, and other optimizations.

Achieved significant month-over-month cost reductions as high as 80% for clients This is a blog published by CloudCheckr. Executive Summary Established in December 2019 in Seoul, South Korea, SmileShark is a fast-growing managed service provider (MSP) with a focus on bringing cloud strategy, security, and support to customers’ Amazon Web Services (AWS) environments. SmileShark’s customer base began with the gaming industry and has also expanded to startups, small and medium-sized businesses (SMBs), and public sector clients. SmileShark’s leadership team includes engineers from top-tier gaming companies. They knew that they needed a cloud management tool to help their customers optimize AWS costs. Shortly after the company’s inception, they began using CloudCheckr CMx to optimize, modernize, and manage customer workloads running on AWS. With CloudCheckr, SmileShark has achieved month-over-month savings as high as 80% for gaming customers and reduced one gaming company’s AWS bill from $300,000 to $100,000 a month. SmileShark’s startup and SMB customers have also seen the cost saving capabilities in CloudCheckr CMx through detailed Reserved Instance purchasing recommendations. The company currently supports more than 150 AWS customers across gaming, startup, and SMB segments, and that number is growing fast. Challenges for a Rapidly Growing AWS Partner From day one, SmileShark rapidly grew into a strategic AWS Partner in Korea. In September 2020, SmileShark became one of the fastest AWS Partners upgraded to an AWS Advanced Tier Consulting Partner. In the company’s first two years alone, they became an AWS Solution Provider and an AWS Public Sector Partner, and they have been technically validated in three AWS Service Delivery Programs for Amazon CloudFront, Amazon EC2 for Windows Server, and Amazon RDS. In 2021, SmileShark received an AWS Rising Star of the Year Award from AWS Korea for their outstanding performance. That expertise has helped SmileShark attract customers and differentiate themselves from the competition. However, early on, SmileShark’s leaders recognized the need for other tools to stand out in the market. They sought out a high-quality cloud management solution to conduct efficient and accurate billing and optimize customer costs. “One of our employees had already experienced a cloud management platform,” said Moowon Kim, Global Business Development Manager at SmileShark. “We knew that to run our business on AWS, we needed a cloud management platform.” Kim and team researched several cloud management platforms, including both local and global solutions. SmileShark chose CloudCheckr CMx because it supports all AWS regions and would help them expand their reach globally. Within mere days after founding the company, SmileShark began building a robust tech stack that includes CloudCheckr CMx to help manage clients’ costs. With the efficient billing and cost management tools in CloudCheckr CMx, SmileShark was able to go to market promptly and see rapid growth in the AWS Partner ecosystem. Efficient Cost Allocation Through Savings Plans With CloudCheckr CMx in place, SmileShark immediately accelerated their growth. One of the biggest attractors to CloudCheckr was the ability for SmileShark to better allocate costs for their customers. With the List Price Translation feature in CloudCheckr CMx, SmileShark could charge customers appropriately for bundled services, including Reserved Instances and Savings Plans. This feature was important, Kim said, because compared to other solutions, “CloudCheckr actually helped to provide the correct usages and prices.” CloudCheckr began supporting AWS Savings Plans in November 2019 , the same month that AWS introduced this discount for purchase commitments. This timing was ideal for SmileShark to help them take advantage of these discounts. The feature gives SmileShark a way to apply custom charges in the right places so that they and their customers receive the benefits of these discounts. Kim also said that he regularly checks the Advanced Grouping report in CloudCheckr CMx. This report helps SmileShark group costs by multiple categories to generate more detailed breakdowns of AWS costs, including blended, unblended, and list costs as well as AWS credits. “The customer noticed a while later that the CPU was overprovisioned, so we checked all the resources in CloudCheckr. It was quite easy to check how many instances they have and all the other components.” Moowon Kim, Global Business Development Manager at SmileShark Cost Optimization Success Stories In addition to the cost allocation features in CloudCheckr CMx, SmileShark has also used the platform to help customers optimize costs. In some cases, these cost optimization tools have helped SmileShark’s customers decrease cloud costs by 67% or more month-over-month. Gaming companies are drawn to the elasticity of the cloud, Kim said, because their demand changes over time. They tend to dramatically increase AWS workloads over a period of several months to a year as they accept a large number of new users. Often, when a company launches a new game, they need less computing power during the development and testing phases and then much more after launch as new users sign up and begin playing. After a few months, demand naturally decreases, and so does the need for additional CPU. For one gaming company, Kim explained, SmileShark lowered their monthly cost from over $300,000 to about $100,000. The company wanted to launch their game service through AWS, starting in November with testing and launching in February. “The customer noticed a while later that the CPU was overprovisioned, so we checked all the resources in CloudCheckr,” Kim said. “It was quite easy to check how many instances they have and all the other components.” This company wasn’t the only SmileShark customer wasting resources. CloudCheckr’s reports showed another company with unused EC2 instances. After optimization, SmileShark reduced the client’s monthly costs from $100,000 to just $20,000 a month — an 80% decrease. Other SmileShark customers across industries have seen greater cost optimization with CloudCheckr. The startups and SMBs working with SmileShark typically increase their workloads and users slowly but steadily over a long period of time. For these customers, Kim explained, CloudCheckr serves as an integral cost saving tool by providing Reserved Instance purchasing recommendations. Deeper Insights and Increased Visibility into AWS Environments Kim said that SmileShark employees have found it very easy to see resources in CloudCheckr versus uncovering savings in AWS native tools. He explained that in AWS it can sometimes be difficult to identify older resources. “Faster optimization is really important for our customers,” said Kim. “CloudCheckr helps us to check their resources easily.” Kim said that he uses the Cost Savings report in CloudCheckr to see possible monthly savings, easily check idle and unused resources, and review Reserved Instance purchasing recommendations. “SmileShark has a lot of accounts to optimize,” Kim said. “We’re checking through Cost Savings, and it’s way faster [than native tools]. I really like to use the Cost Savings report in CloudCheckr CMx to check their idle resources.” Continued Growth with CloudCheckr SmileShark is continuing to grow and expand into other markets. Kim said that the company is planning to grow their AWS partnership and working toward becoming an AWS Premier Consulting Partner, the highest tier awarded. As SmileShark grows, Kim said he plans to look at the security and compliance features in CloudCheckr CMx to help expand their solutions. These tools are invaluable, he said, for an AWS Consulting Partner and for businesses working to deepen their AWS partnerships. Kim also expressed gratitude for the one-on-one support and training that CloudCheckr account representatives provide for SmileShark. He said the technical support reps are just an email away, and the CloudCheckr team is always receptive to feedback and ideas for new services. Additionally, the regular meetings every two weeks with the CloudCheckr team, said Kim, are “really helping our business.” ※All content provided by smile shark is protected by relevant laws.

Intro: First step to AWS Lambda Not many people choose Lambda as their new service Lambda is a compute service that lets you run without provisioning or managing servers. It is an essential service for automating AWS environments I learned AWS Lambda with little experiences about code But the advantage of being able to customize the various environments of AWS for automation and integration, motivated and challenged me to use lambda Load CloudWatch Metric Index through Lambda [Summary] We worked on cloning Lambda for the first time CloudWatch is the most used AWS service for monitoring AWS infra environment We synced this service and lambda for delivering monitoring index to community messenger called slack [Purposes] Deliver CloudWatch metric index to slack channel by running Lambda code If we achieve that goal, we don’t need to check CloudWatch monitoring information by accessing user account console. We can implement the system that can directly requests to slack about CloudWatch information of various accounts. It detects disabilities and enhances the readability by loading each essential CloudWatch metric index. [Implementation] 1. pip Package management system Install pip package to set up modules for training C:\Users\user>curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py C:\Users\user>python get-pip.py C:\Users\user>python -m pip install –upgrade pip 2. Essential modules Installation C:\Users\user>pip install boto3 certifi chardet idna json requests 3. Compress(.zip) modules to use Lambda C:\Users\your account\AppData\Local\Programs\Python\Python37\Lib\site-packages 1. Create IAM policies IAM - Policy - Create Policy Paste Jason policy code "Version": "2012-10-17", "Statement": [ { "Sid": "VisualEditor0", "Effect": "Allow", // "Action": [ "cloudwatch:DescribeAlarmHistory", "cloudwatch:GetDashboard", "cloudwatch:GetMetricData", "cloudwatch:DescribeAlarmsForMetric", "cloudwatch:DescribeAlarms", "cloudwatch:GetMetricStatistics", "cloudwatch:GetMetricWidgetImage" ], "Resource": "*" } ] } 2. Create IAM roles IAM - roles - create roles Lambda - choose created policies - create roles 1. Create Lambda functions Lambda - functions - create functions write new - function names - runtime - running roles - existing roles - Create random function names - Choose the language and version when you write functions - Apply roles that you created 2. Slack Settings Slack - Apps - Create Bots - Copy API Token 3. Write Lambda functions CloudWatch - Index - Choose Index - Copy sources "metrics": [ [ "AWS/EC2", "CPUUtilization", "InstanceId", "i-0cf3d15721cedbf7e" ] ], "view": "timeSeries", "stacked": False, "stat": "Maximum", "period": 300, "width": 914, "height": 250, "start": "-PT3H", "end": "P0D", "timezone": "+0900" } - false → False to correct the grammar function codes - work - modules(.zip)upload Create files - Write sample codes import json import boto3 import requests cloudwatch = boto3.client('cloudwatch') metric_sources = [ { "metrics": [ "AWS/EC2", "CPUUtilization" ], "view": "timeSeries", "stacked": False, "region": "ap-northeast-2", "timezone": "+0900" } ] def metric(event, context): for metric_data in metric_sources : metric_data = json.dumps(metric_data) #print(metric_data) image_data = cloudwatch.get_metric_widget_image(MetricWidget=metric_data) #print(image_data) slack_params = { "filename":"test.png", "token":"SLACK BOT의 token 값을 넣어 주시면 됩니다", "channels":['#aws-db-slowquery-noti <-와 같이 채널 명칭을 넣어주세요.'] } image = {'file': image_data['MetricWidgetImage']} requests.post("https://slack.com/api/files.upload", params=slack_params, files=image) -Paste CloudWatch metric sources to metric_sources -Paste Token value of token Slack Bots -Type channels name (ex. #awschannels) 4. Lambda functions test Lambda - Choose functions - Test -Set-up CloudWatch metric information will be printed out when functions run Review: Potentials of Lambda With this training process, We sync AWS services to trigger functions automatically to use AWS Lambda more flexibly and we will implement methods to use AWS Lambda more easily. Lambda is an essential AWS service to implement the automation environment. Our final goal is to get custom abilities for the automation environment and we need to get used to Lambda by practicing it.
