Developer Experience and Productivity Metrics
Combine DORA, SPACE, and DevEx to assess developer experience. Choose useful measures, protect survey respondents, and test changes against work outcomes.
-
-
Platform Adoption and Developer Support
Platform adoption needs a usable route, funded support, and decisions users understand. Connect onboarding, migration, feedback, and contributions to that work.
-
Golden Paths and the Platform Contract
A golden path needs an operating agreement: supported choices, update and migration responsibilities, and a clear process for exceptions.
-
Parts of an Internal Developer Platform
A platform joins discovery, request fulfillment and continuing operation. Evaluate those capabilities separately and trace what happens after submission.
-
Platform Engineering Responsibility Boundaries
Define who operates platform capabilities, how support is shared, and how agreed limits and exceptions protect engineering capacity.
-
Choosing a Managed Kubernetes Platform
Platform composition and operating responsibility are separate choices. Compare support deadlines, workload requirements, retained controls, and cost.
-
Kubernetes Isolation, Policy, and Upgrades
Additive permissions still deny unallowed access. Verify quota enforcement, policy scope and the distinction between minor upgrades and security patches.
-
Kubernetes Networking, Storage, and State
Follow PVCs to their PV policies, distinguish endpoint readiness from traffic cutoff, and budget hooks and cleanup together during shutdown.
-
How Kubernetes Reconciles Declared State
An accepted manifest starts reconciliation. Confirm the intended rollout, inspect failures, and verify service behavior before declaring a release successful.
-
Containers, Images, and Their Boundaries
Deleting a file in a later image layer does not remove it. The removal is recorded as an entry; the bytes are still in the layer below.
-
CI/CD Delivery System Comparison
Compare execution isolation, automatic tokens, supplied credentials, and internal build authorization to determine what a delivery job can reach.
-
Infrastructure and Configuration as Code
Your code says what should exist. The state file says what the tool believes exists. The cloud knows what actually exists. Three answers, one system.
-
Progressive Release and Change Compatibility
A rollback needs a compatible target. Plan schema transitions, flag lifecycles, and recovery decisions before exposing a release.
-
CI/CD Artifacts, Verification, and Promotion
Keep the release artifact tied to its checks. A matching source revision alone does not establish that staging and production run the same software.
-
Software Delivery as a Flow
A fictional change takes two days to write and six weeks to reach a user. Trace its waits, work, and rework to decide what to improve.
-
Enterprise Integration and Consistency
The message was delivered and the order was never shipped. Both statements can be true at once, and only one of them is what the business asked for.
-
API Management and Service Delivery
A gateway can validate credentials and enforce shared policies. Services still need authorization tied to their data and current business state.
-
API Contracts, Compatibility, and Retirement
API changes need both a clear compatibility contract and evidence of consumer impact. Errors, retry safety, and retirement are part of that work.
-
Cloud Native and Service Boundaries
Service decomposition can leave dependencies intact. Examine ownership, contracts, and shared failures before choosing a distributed topology.
-
Infrastructure Engineering as a Lifecycle
Support deadlines, patches, and configuration changes need continuing ownership. Connect coverage, tested images, and service-aware rollout in one lifecycle.
-
Hybrid Cloud and Multicloud Design
A second cloud does not make a system more available by itself. It adds a boundary, and whether that boundary helps depends on what you put across it.
-
Azure, AWS, and Google Cloud Compared
Compare inherited grants, SCP restrictions, and network scope by mechanism. Similar diagrams can require different controls and operating arrangements.
-
Accounts, Guardrails, and the Landing Zone
A cloud foundation establishes access, policy, ownership, and connectivity. Plan the boundaries early and verify inherited controls as requirements change.
-
Cloud Networking and Connectivity
In AWS, a private subnet has no direct route to an internet gateway. Exposure also depends on addresses, filtering rules, and indirect paths.
-
Cloud Execution Models and Responsibility
Managed services transfer specific duties. Compare responsibility boundaries, storage lifetimes, recovery, and total cost before choosing an execution model.
