DSI, based in South San Francisco, works from more than 25 years of experience building technology for large multinationals, developing configurable solutions for industry leaders rather than off-the-shelf products. The firm draws on over 2000 engineers to take on complex projects, with a focus centered on cloud technologies and emerging platforms rather than legacy infrastructure alone.
Services span cloud architecture and hosting across MS Azure, AWS, Google Cloud, MS Hyper-V, VMware, and HP-UX virtualization, paired with application development in C#, Python, Java, and PHP. Data engineering work covers Big Data tools including Hadoop, Kafka, GigaSpaces, Logstash, Kibana, Grafana, Google Analytics, and machine learning, while database management extends across MS SQL, Oracle, MySQL, PostgreSQL, MongoDB, Cassandra, Hazelcast, and DynamoDB. Systems integration and microservices/API work round out the technical scope, allowing DSI to modernize and connect existing environments rather than rebuild from scratch each time.
One documented engagement involved a large resorts and entertainment group whose legacy systems needed modernization. DSI migrated those systems to the cloud and built a new custom platform based on microservices architecture, hosted on Microsoft Azure. The project reflects the firm's applied approach to cloud migration and modernization: replacing aging infrastructure with a distributed, cloud-hosted architecture rather than a lift-and-shift of old systems.
