TechWave's existing on-premises infrastructure limited its ability to efficiently manage and analyze the growing volume of data generated by client projects. The company struggled with:

1. Data Silos:
Different teams maintained separate databases, leading to inconsistency in data quality and reporting.

2. Scalability Issues:
As the company grew, its IT infrastructure could not scale effectively to meet demand.

3. Limited Analytics
Capabilities: The inability to harness real-time data analytics hindered decision-making and project management.

To address these challenges, TechWave aimed to implement cloud and big data solutions that would:

1. Integrate data across teams to eliminate silos.
2. Provide scalable storage and computing resources.
3. Enhance analytics capabilities for better business insights and decision-making.

Phase 1: Needs Assessment
TechWave conducted a comprehensive assessment of its current IT infrastructure, data management practices, and analytics needs. Key stakeholders from various departments were involved in identifying requirements and pain points.

• Scalability and flexibility.
• Cost-effectiveness.
• A wide range of tools and services for data analytics.

Phase 3: Migration to the Cloud
The migration process involved several steps:

1. Data Migration: TechWave utilized AWS DataSync to transfer existing data from on-premises databases to Amazon S3.
2. Application Migration: Key applications were migrated to AWS Elastic Beanstalk, allowing for easier deployment and scaling.
3. Database Migration: The company migrated its databases to Amazon RDS for better management and scalability.

Phase 4: Implementing Big Data Solutions
TechWave adopted AWS services for big data processing:

• Amazon EMR:For processing large amounts of data using Apache Hadoop and Spark.
