What does a Rackspace cloud Servers developer do?
A Rackspace cloud Servers developer builds and automates applications that provision, manage, and connect to virtual machines through the Rackspace Cloud Servers API. This role focuses on writing code that interacts directly with regionalized API endpoints to create server resources rather than relying solely on manual clicks in a web interface. The developer handles authentication workflows by obtaining Identity tokens and injecting them into API headers to authorize every request. They also configure secure network access patterns so external systems can reach these servers over public IPs or private ServiceNet connections.
- Write scripts or application modules that call the Rackspace Cloud Servers API to create, list, and manage virtual machine instances. This work involves selecting the correct regional endpoint from the service catalog and sending REST requests via tools like cURL or custom code libraries. The developer ensures each request includes the proper X-Auth-Token header obtained from the Cloud Identity API to validate access rights for the specific project.
- Implement secure SSH connectivity by generating public-private key pairs and adding the public keys to the account or region settings. The developer configures authorized_keys files on the servers to allow secure logins without passwords. They document which keys correspond to which environments and provide runbooks that explain how to connect to new instances safely from local machines or CI/CD pipelines.
- Integrate server network addresses into deployment flows by retrieving public IPv4 or IPv6 addresses and private ServiceNet IPs from the API response data. This allows applications to route traffic correctly between internal services within the same data center and external users on the internet. The developer maps these connectivity needs to the specific server configuration to ensure low-latency communication and proper firewall rules are in place.
How to hire a Rackspace cloud Servers developer on Upwork
Step 1: Post a job
Define your infrastructure automation needs clearly to attract developers who specialize in the Rackspace Cloud Servers API. Use the Job Post Generator powered by Uma™, Upwork's Mindful AI to draft a precise description from a few sentences about your project. You can write a new post, update a saved draft, or reuse an existing post to start hiring immediately.
- Specify that the freelancer must authenticate requests using the Rackspace Cloud Identity API and include the X-Auth-Token header in all calls.
- List requirements for selecting correct regionalized API endpoints from the service catalog for your target data center.
- Request experience with configuring SSH key management and integrating public IP or ServiceNet connectivity into deployment flows.
Step 2: Evaluate candidates
Look for portfolios that demonstrate working code scripts automating server provisioning and management via the Cloud Servers API. Uma can run instant video interviews and build shortlists with side-by-side comparisons to help you assess technical fit quickly.
- Verify that past projects include modules handling Identity tokens for authenticated API calls rather than manual console clicks.
- Check for documentation showing how the candidate mapped server network connectivity needs to public IP and ServiceNet usage.
- Confirm the developer authored runbooks describing secure SSH login procedures and key pair generation for specific regions.
Step 3: Interview your top choices
Discuss specific workflows such as obtaining Identity tokens and calling Cloud Servers API operations to gauge practical knowledge. Schedule and conduct these interviews within Upwork Messages to receive an immediate transcript and summary after each conversation.
- Ask how they handle endpoint selection when copying base URLs from the service catalog for different projects.
- Question their approach to updating authorized_keys manually versus adding public keys to the account via API.
- Explore their method for retrieving server network addresses to connect external systems within the region securely.
Step 4: Agree on scope and begin work
Set clear milestones for delivering automation scripts and API authentication modules before starting the contract. Use Upwork Messages and the contract workroom for communication and project management, plus identity verification, payment protection, hourly tracking, and project funds for security.
- Define deliverables as working code that creates, manages, and lists server resources through the v2 API.
- Require a deployment guide specifying regional endpoint selection and SSH connection steps for your team.
- Establish integration notes that detail how public IPs and ServiceNet addresses support your application architecture.
