CONVERT GCP PROJECTS TO TERRAFORM
It can be tough to try to reverse engineer an existing project that has never used terraform. Terraformer can look at an existing project and generate the corresponding terraform code for you. I tried it out on an existing legacy project which used Google Cloud Storage, BigQuery and various service accounts. The setup was a little tricky so I put together a script to simply things. The script assumes you have gcloud setup or a service account key/impersonation and you may need to adjust the –resources parameter.

JAVA 17 LTS: ENTERPRISE FEATURES GUIDE
Major Features in Java 17 LTS Enhanced Random Number Generation Pseudo-Random Number Generators (PRNGs) are getting a major update in Java with the release of JEP 356. New interfaces and implementations make it easier to use different algorithms interchangeably and offer better support for stream-based programming. This is a great improvement for Java developers who require randomness in their applications.

KAFKA VS GOOGLE CLOUD PUBSUB: 2020 COMPARISON
Feature Confluent Cloud Kafka Google Cloud Pubsub Notes Data Retention Set retention per topic in Confluent Cloud, including unlimited retention with log compaction. Retains unacknowledged messages in persistent storage for 7 days from the moment of publication. There is no limit on the number of retained messages. Have to write custom subscriber/publisher to save beyond 7 days [L] + ongoing BAU [S] Replay A consumer request an “offset”, however the retention period is dictated by the broker config “Snapshots” can be created for later replay by these are limited to 7 days as per retention policy. As per above, a custom subscriber/publisher to save/replay message. [L] + ongoing BAU [S] Message Ordering Yes, within a partition, In general, messages are written to the broker in the same order that they are received by the producer client. No, Pub/Sub provides a highly-available, scalable message delivery service. The tradeoff for having these properties is that the order in which messages are received by subscribers is not guaranteed. While the lack of ordering may sound burdensome, there are very few use cases that actually require strict ordering. Delivery Semantics Exactly-once delivery semantics At-least-once, exactly once possible with dataflow Latency Advertised at being able to “Achieve sub 30 ms latency at scale”, no mention of this in SLA. Pub/Sub does not guarantee message delivery latency Uptime “Service Level” Monthly Uptime Percentage of at least 99.95%.Is this 99.95% of GCP’s 99.95%? “Service Level Objective” Monthly Uptime Percentage to Customer of at least 99.95% Both offer credits to account if not met but this is unlikely to be suitable for an enterprise org Schema Registry Yes for Avro schemas and very new (GA August 2019) No, Data Catalog is in beta and could be used to build one [XL] IAM / ACL “Preview” for Role/SAML, ACLs You are provided auth keys that you need to store/share/rotate. These could be stored in Cloud KMS, however, this would need to be automated [XL] + ongoing BAU [M] Standard Google IAM Encryption Yes in transit and at rest with NO payload encryption. Clients are responsible for writing custom encryption/decryption connecting to (e.g) Cloud KMS. A custom library would need to be written that is used by everyone for publishing and subcribing [L] Cloud KMS(HSM/Software/BYOK/External Key Manager) with CMEK VPC Security Unknown/No, can Confluent Cloud be made to respect VPC service controls? VPC Service Controls protection applies to all push and pull operations except existing Pub/Sub push subscriptions Stream Processing “fully-managed KSQL”, no kafka streams, would have to run Kafka Streams/Storm cluster connecting to Confleunt Cloud which is likely to introduce latency Apache Beam / Cloud Dataflow fully managed Costs per 130GB $37 $39 Based on example calc on confluent and google pricing calc Priority Queues Yes No, but can segregate by topic Multi-zone high availability Not advertised “Contact Confluent” Yes
