Opensurvey 'The new future of data’ Opensurvey redefines the value of surveys with IT technology and open the era of customer experience management. With research product, they collect the data easily and analyzes customer thoughts and behaviors specifically to help companies to make right decisions based on data. Furthermore, Opensurvey is positioning themselves as a business partner that supports companies’ continuous growth by managing customers, users, and employees survey experience. Name Opensurvey Area Customer data bussiness Estab. Feb, 2011 Site https://www.opensurvey.co.kr/ Difficulties in IDC and Cloud environment Challenges Opensurvey frequently found hardware problems while using IDC and local cloud. Also, there was a hassle between the process of bonding data distributed to two sites and Complex processes occurring based on VM. So, Opensurvey decided to implement Kubernetes to fix the problem and considered migrating IDC to the cloud environment. Why SmileShark? Opensurvey used IDC and local cloud at the same time to protect data loss. But they encountered various operational difficulties while using IDC and local cloud. As a result, they needed to migrate their services to AWS for flexible resource scaling and cost optimization to provide better services for the customers. However, it was important how to migrate more than 1 million survey data collected and analyzed every month without losing any data. So, they wanted to migrate safely to AWS with technical supports from SmileShark, AWS Advanced consulting partner specializing in migration. Adopting Kubernetes to increase organizational flexibility Increased development flexibility Opensurvey leverages various AWS services to increase reliability. In particular, Opensurvey was able to scale up and down flexibly by migrating workloads to Kubernetes and simplified the deployment process which improved developer productivity and made efficient use of resources. Through this, Opensurvey was able to manage unexpected traffic stably even if multiple enterprise customers collected large amounts of data in a short period of time. Since Opensurvey uses the Kubernetes environment, it is easy to apply Spot instances, and when developing new services, Spot instances reduce instance costs by more than 70%, increasing the speed of new development by using them without burden. Increased business flexibility Opensurvey successfully migrated from IDC to AWS through AWS Advanced Partner, SmileShark. In addition, it was possible to respond flexibly to issues compared to the existing IDC by receiving an instance type suitable for the platform characteristics through a partner. Furthermore, increased flexibility allows Opensurvey to accept the requirements of the enterprise customers, enabling business and industry expansion. Hyun-min Park from Opensurvey backend chapter lead developer explains, “As Opensurvey grows, there are many difficulties in stably operating the service through the existing on-premises environment, so we adopted AWS services for greater flexibility.” Park also says, “In addition, we utilize AWS managed services to minimize the developer's resources and operate the service reliably.” Transition from a consumer data platform to an experience management platform Opensurvey Next Step Opensurvey is opening a new future of data by connecting companies and consumers/users/customers based on survey data. Since the launch of ‘Opensurvey’ in 2011, they have developed a survey-based data collection and analysis product, and launched (Feedback.io) in 2022 to expand the product so that not only customers, users but also employee’s experience can be accumulated and managed through survey based data. Currently, the need for continuous user data collection and experience management is increasing, especially in digital companies, so they plan to continuously develop data collection and analysis products as a business partner for mutual growth.

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.

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.
