Voicy: AWS Migration with 24% Cost Optimization

Voicy

About the client: Voicy is a platform for audio memes that boasts over 500,000 sound clips created by a broad community of users. Challenges: Voicy encountered several issues that led to their partnership with SotaTek. Their current infrastructure on Azure was unable to accommodate their demands, necessitating a switch to AWS to enhance scalability and performance. Key obstacles included: - Platform migration: Moving from Azure to AWS. - Tight timeline: Completing the migration within one month. - Architecture overhaul: Transitioning from a monolithic architecture to a microservices-based structure for better scalability and flexibility. - Compatibility issues: Ensuring that AWS services aligned well with existing functions. - VM dependencies: Addressing inefficiencies stemming from manual virtual machine maintenance. - Cost optimization: Reducing operational expenses through AWS solutions. Solutions: SotaTek created a customized solution for Voicy based on the AWS Well-Architected Framework, providing a secure, high-performing, and economical cloud environment. The architecture was redesigned from a monolithic to a scalable microservices architecture using an effective AWS tech stack, which included ECS for container management, RDS for databases, CloudWatch for monitoring, Lambda for serverless operations, and S3 for storage. The Database Migration Service (DMS) and DataSync facilitated smooth data transfer, while Redshift aided in data warehousing, and OpenSearch improved search functionality. SotaTek also refactored code for AWS compatibility, replacing Azure-specific elements and optimizing costs for operational efficiency. Results: Voicy successfully migrated all services from Azure to AWS within the established timeframe, achieving a modern and scalable infrastructure. This transition led to a 24% reduction in cloud expenses and improved scalability through containerized microservices on Amazon ECS. The multi-AZ deployment ensures high availability, and AWS-managed services simplify operations, enabling Voicy to effectively manage surges in user activity.

Fellaz Web3 IDO Platform Development

Fellaz

Client Overview: Fellaz, an innovator in Web3, set out to develop a multichain IDO platform designed to transform investor participation in token pre-sales. This platform accommodates ICOs and INOs, allowing users to invest in carefully screened projects. Challenges: Fellaz encountered multiple technical and operational issues while developing their multichain IDO platform. They required a seamless system to handle the ICO and INO processes, which involved distinct Whitelist and Community phases with specific criteria. A major challenge was ensuring robust multichain support for Ethereum and Arbitrum networks, along with implementing a payment system limited to Fellaz Tokens (FLZ). Additionally, integrating the new platform with existing systems presented further difficulties. To address these challenges and build an efficient, user-friendly platform, Fellaz collaborated with SotaTek, drawing on their expertise in blockchain and Web3 technologies. Solutions: SotaTek partnered closely with Fellaz to establish clear objectives and timelines while employing Agile methodologies for flexibility and effective delivery. They constructed the platform in line with Fellaz's specifications and vision, using the following technology stack: - AWS Services: For scalable cloud hosting, efficient content distribution, secure certificate management, and reliable traffic distribution. - Blockchain: Solidity smart contracts for EVM chains to facilitate secure multichain transactions. - Frontend & Backend: ReactJS for an interactive user interface and NodeJS for a versatile backend. - Data Management: MySQL and MongoDB for data storage, Redis for caching, and Amazon MQ for messaging. Results: Fellaz successfully launched their groundbreaking IDO platform, effectively meeting all initial objectives. Fellaz's feedback on SotaTek: "I am pleased with the support and quality of work from SotaTek. They were always responsive, even on weekends and holidays, and constantly provided positive assistance. I sincerely appreciate all the team members."

UBet Crypto: Blockchain & AWS Development

Ubet Crypto

**Client Overview:** UBet is a sports betting and casino platform that utilizes blockchain technology to provide a secure, transparent, and user-centric experience. **Challenges:** UBet encountered the need to develop a platform that could accommodate 30,000 concurrent users while maintaining low latency for an uninterrupted user experience. Security was a top priority, necessitating safeguarding for both non-custodial wallets (against phishing, malware, and key loss) and custodial wallets (to address counterparty risks and internal vulnerabilities). Additionally, scalability and performance efficiency were crucial to accommodate increasing user demand without sacrificing stability or speed. **Solutions:** SotaTek delivered a comprehensive solution that fused AWS services with blockchain expertise to fulfill UBet’s needs: 1. **Blockchain Implementation:** Created secure systems for cryptocurrency betting and wallet integration. 2. **Real-Time Event Processing:** Utilized AWS MSK for effective data ingestion and analysis, enabling live odds updates and real-time insights. 3. **Security Enhancements:** Implemented AWS WAF for protection against cyber threats and AWS KMS for data encryption, complying with GDPR and PCI DSS standards. 4. **Scalability:** Employed AWS ECS with Auto Scaling to manage peak traffic. 5. **Data Management:** Deployed RDS Aurora, Redis, and MongoDB Atlas for data storage. 6. **Third-Party Integration:** Connected services like Intercom, Sportradar Pixel, RudderStack, and Contentful for data analysis and user engagement. 7. **Payment Gateway Integration:** Facilitated smooth fiat-to-crypto transactions for user convenience. **Results:** The decentralized betting system enabled UBet to support up to 30,000 concurrent users with low latency and high responsiveness. The integration of third-party tools improved marketing capabilities through sophisticated data tracking and analysis. The payment gateway integration allowed for direct fiat-to-crypto transactions on the platform, resulting in a 30% increase in transaction volume and enhancing user engagement and financial activity.
