Google Cloud PDE: Choosing Dataflow, Dataproc, or BigQuery
Dataflow, Dataproc, and BigQuery all process large datasets on Google Cloud, but they solve different processing problems. Dataflow is a managed execution service for Apache […]
Google Cloud PDE: Pub/Sub Delivery Semantics
Reliable event ingestion depends on understanding what a messaging service guarantees and what the application must still guarantee for itself. Google Cloud Pub/Sub can provide […]
Google Cloud PDE: Dataplex Universal Catalog
Google Cloud’s data-catalog story has changed names. Dataplex Universal Catalog has transitioned to Knowledge Catalog, an AI-oriented catalog and context layer within Google’s broader data […]
Google Cloud PDE: Choosing Bigtable, Spanner, or BigQuery
Bigtable, Spanner, and BigQuery can all store very large amounts of data on Google Cloud, but that similarity is superficial. Bigtable is a wide-column, key-oriented […]
Google Cloud PCNE: HA VPN vs Cloud Interconnect
Hybrid connectivity on Google Cloud is not a one-dimensional choice between “VPN” and “private circuit.” HA VPN and Cloud Interconnect solve related connectivity problems with […]
Google Cloud PCNE: Cloud NAT, Private Google Access, and Private Service Connect
Cloud NAT, Private Google Access, and Private Service Connect are often grouped under “private networking,” but they solve different problems. Cloud NAT provides source network […]
Google Cloud PCNE: Load Balancing
Google Cloud Load Balancing is a family of services, not one product with a single behavior. The correct design depends on protocol, whether Google terminates […]
Google Cloud PCNE: Network Connectivity Center
Network Connectivity Center (NCC) gives Google Cloud a hub-and-spoke control model for connecting VPC networks, hybrid sites, and supported network appliances or gateways. It is […]
Google Cloud PCNE: Cloud Armor, Cloud NGFW, and VPC Firewall Rules
Google Cloud offers several network and application security controls that are easy to collapse into the word “firewall.” VPC firewall rules and firewall policies govern […]
Google Cloud PCSE: Workload Identity Federation vs Service Account Keys
External workloads often need to call Google Cloud APIs, but the way they obtain credentials changes the security model dramatically. A downloaded service-account key is […]
Google Cloud PCSE: VPC Service Controls and Access Context Manager
Identity and Access Management answers whether a principal is allowed to perform an action. VPC Service Controls adds a different question: even if the principal […]
Google Cloud PCSE: CMEK, Cloud HSM, or Cloud EKM?
Google Cloud encryption discussions often mix together three terms that describe different layers of the design. Customer-managed encryption keys, or CMEK, describe an integration in […]
Google Cloud PCSE: Binary Authorization and Artifact Analysis
Container security is not solved by scanning an image once, and it is not solved by blocking unsigned images without knowing what the signature means. […]
Google Cloud PCSE: Security Command Center, Threat Detection & Cloud IDS
Security Command Center, Event Threat Detection, and Cloud IDS all surface security findings, but they occupy different positions in the detection architecture. Security Command Center […]
