Altostratus and AWS drive digital transformation in the energy sector
In a context of rapid growth and international expansion, one of the leading renewable energy companies in the Spanish market adopted a cloud-first strategy to modernize its technology infrastructure. With operations in key markets such as Spain, Italy, Japan, the United States, Chile, Australia, and Mexico, the company needed a scalable, secure, and efficient platform to support its evolution.
Working with Altostratus, part of Telefónica Tech, the company embarked on an ambitious migration project to AWS, optimizing costs while ensuring maximum performance and security.
From traditional infrastructure to an agile and secure cloud
The company was operating on an infrastructure hosted by an external hosting provider, whose service had reached end of life. This situation posed multiple challenges:
- Lack of flexibility and scalability to support business growth and geographic expansion.
- High operational complexity, with fragmented management across hosting services and on-premises environments in different locations.
- Security and compliance risks due to reliance on shared services and a decentralized infrastructure.
- Cost inefficiencies, with high operational expenses in storage, networking, and hardware maintenance.
Aware of the complexity of these challenges, the company partnered with Altostratus to define and implement a cloud strategy tailored to its specific needs.
The Solution: A cloud-first ecosystem with AWS technology
To address these challenges, Altostratus designed a four-phase cloud strategy: assessment, landing zone, migration, and modernization, ensuring a smooth transition with no impact on business operations.
With the goal of ensuring maximum performance and security, Altostratus implemented a strategic approach that optimizes operations and reduces complexity, integrating AWS best practices:
- Simplified management with AWS Control Tower and AWS Organizations for centralized and secure administration of cloud resources.
- Seamless connectivity, ensuring smooth communication across all business areas with AWS Transit Gateway and secure VPN.
- Resource optimization, migrating servers to Amazon EC2 and databases to Amazon RDS to improve performance and reduce costs.
- Intelligent automation, managing the infrastructure with Terraform and AWS CloudFormation for efficient deployments.
- Maximum security and control, implementing data encryption and network segmentation for enhanced protection.
Results: efficiency, security, and cost savings
The impact of the migration to AWS was significant, delivering key improvements in performance, security, and business profitability. Thanks to a well-defined and executed cloud-first strategy, the company was able to optimize resources and reduce costs without compromising operational stability:
- 23% cost reduction compared to the previous infrastructure.
- Greater operational efficiency, with provisioning times reduced from weeks to minutes.
- Enhanced security with advanced IAM policies and continuous auditing.
- High availability and improved performance, thanks to multi-AZ deployments and latency optimization with AWS Global Accelerator.
Towards a secure and efficient digital future
Beyond the migration, the company continues to evolve its cloud strategy to drive growth and optimize operations.
With AWS and Altostratus as strategic partners, the company continues to adopt advanced solutions that enhance security, improve performance, and ensure an infrastructure ready to face the challenges of the digital future.
