I'm probably forgetting some, but this is a fairly comprehensive list of the cloud services I use for work:
GCP: This is primary cloud provider and we try to stay in-cloud as much as possible.
AWS: Legacy services that weren't worth the hassle porting to GCP, like s3. Also, we just acquired a company who's product is fully rooted in AWS, so our footprint has expanded.
MongoDB: MongoDB drives two of the applications that make up our platform.
MailChimp: Transactional emails (technically this is Mandrill but they dropped the branding?)
Confluent: Data pipelines within the application
Hevo: Data pipelines from third-party sources into our BigQuery data warehouse
Pusher: Real-time notification events for one of our legacy applications
New Relic: Performance Monitoring
DataDog: Synthetic Tests
Sentry: Front end monitoring
Elastic: For our application's activity feed
Lokalise: Automated translations using CI/CD
BrickFTP/Files.com: SFTP option for our customers to transmit HRIS files for processing
Cloudinary: Image transformations
Pager Duty: MTTR tool
Velocity Code Climate: A metrics tool which allows you to measure the performance of your engineers. I know that might sound controversial to some, I would encourage you to read the book Accelerate to understand the value such a tool provides.
Atlassian JIRA/confluence: Project Management
Github: Source Control
Okta: Single-Sign On
CircleCI: Continuous Integration & Delivery. Check out my post A Litmus Test for CircleCI to understand why we picked Circle
