Run your fault-tolerant workloads cost-effectively with Google Cloud Spot VMs

Modern applications such as microservices, containerized workloads and horizontal scalable applications are engineered to persist even when the underlying machine does not. This architecture allows customers to leverage Spot VMs to access Google’s idle capacity and run your application at the lowest price possible. Customers will save 60 – 91% off the price of our on-demand VMs with Spot VMs. Maximize cost optimization by integrating with Google Kubernetes Engine (GKE) Standard and your scalable applications will seamlessly switch to using on-demand resources when Google needs the Spot VM capacity back.Available in Preview today, customers can begin deploying Spot VMs in their Google Cloud projects for:Improved TCO: With a maximum discount of 91% over on-demand VMs, applications that can take advantage of Spot VMs will quickly see these savings add up. When combining Spot VM with our Custom Machine Types and adding on discounted Spot GPU and Spot local SSD, customers can maximize their TCO without sacrificing performance.Better automation: Let GKE handle your deployments to seamlessly mix in Spot VMs with your current infrastructure. Automatically scale up when Spot VMs are available and then gracefully terminate when a preemption occurs, ensuring that work gets done with minimal interruptions. Ease of use and integration: Spot VMs are available globally and are a simple, one-line change to start using. The resources are yours until they need to be reclaimed with no specific duration limits. Take advantage of the new Termination Action property to delete on preemption and clean up after use.Spot VMs are available in every region and most Compute Engine VM families with the same performance characteristics as on-demand VMs. The only difference is that Spot VMs offer a 60-91% discount since the resources may be reclaimed at any time with 30-second notice.Spot VMs are a great fit for a variety of workloads in a broad spectrum of industries including financial modeling, visual effects, genomics, forecasting, and simulations. Any workload that is fault tolerant or stateless, should consider trying Spot VMs as a way to save up to 91% on VM costs! Getting started is as simple as adding –provisioning_model=Spot to your instance request and savings will begin immediately. New dynamic pricing model for Spot VMsTo maximize savings to customers, Google is introducing a new dynamic pricing model that offers discounts from 60% to 91% off of our on-demand VMs. This new pricing model ensures that everyone is getting the best preemptible experience possible by applying a discount to each region based on rolling historical usage for the region. This discount amount may change up to once a month. The discount will always be at least 60% but has the opportunity to move up and down between 60 and 91% off of our on-demand VMs. Customers will also be able to preview the pricing forecast to have visibility to the next pricing change before the new pricing goes live. Starting today, we are announcing price drops for these VM families and locations and dynamic prices will begin in 2022.Preemptible VM instances created through –preemptible will continue to be supported. Preemptible VM customers will not need to make any changes to begin receiving the new pricing. However, preemptible VMs will continue to have a 24h limit. Customers who wish to have no max duration, should switch to Spot VMs to avoid any limits. In order to keep pricing as simple as possible, Preemptibles will follow the same pricing as Spot VMs.Building on our ecosystem, Google Kubernetes Engine (GKE), the leading platform for organizations looking for advanced container orchestration, will also leverage Spot VMs. GKE nodes using Spot VMs are a popular way for users to get the most out of their containerized workloads in a cost effective way. In GKE, Spot nodes can be created by using –spot; preemptible nodes created using –preemptible will continue to be supported. Moreover, starting in GKE v1.21, enable_graceful_node_shutdown is enabled by default to ensure a smooth experience with Spot on GKE. When combined with custom machine types and GKE cost optimization best practices, customers using GKE Spot nodes can achieve even greater savings.NetApp partnership As part of our on-going investment into Spot, we are also strengthening how the GCP ecosystem supports and builds on top of Spot VMs. We are pleased to announce our partnership with Spot.IO to ensure that our joint customers can take advantage of our best pricing ever. “Spot.IO is excited about the market-leading combination of savings and predictability of Google Cloud’s new Spot VMs. Google’s Spot VMs will offer our joint customers more flexibility and versatility in automating cloud infrastructure workloads and create more opportunities to optimize cloud spend while accelerating cloud adoption across micro services, containers, and VM-based stateless and stateful applications.” —Amiram Shachar VP and GM, Spot.IOGet startedSpot VMs are available in Preview now.

Open data lakehouse on Google Cloud

For more than a decade the technology industry has been searching for optimal ways to store and analyze vast amounts of data that can handle the variety, volume, latency, resilience, and varying data access requirements demanded by organizations.Historically, organizations have implemented siloed and separate architectures, data warehouses used to store structured aggregate data primarily used for BI and reporting whereas data lakes, used to store unstructured and semi-structured data, in large volumes, primarily used for ML workloads. This approach often resulted in extensive data movement, processing, and duplication requiring complex ETL pipelines. Operationalizing and governing this architecture was challenging, costly and reduced agility. As organizations are moving to the cloud they want to break these silos. To address some of these issues,a new architecture choice has emerged: the data lakehouse, which combines key benefits of data lakes and data warehouses. This architecture offers low-cost storage in an open format accessible by a variety of processing engines like Spark while also providing powerful management and optimization features. At Google cloud we believe in providing choice to our customers. Organizations that want to build their data lakehouse using open source technologies only can easily do so by using low cost object storage provided by Google Cloud Storage, storing data in open formats like Parquet, with processing engines like Spark and use frameworks like Delta, Iceberg or Hudi through Dataproc to enable transactions. This open source based solution is still evolving and requires a lot of effort in configuration, tuning and scaling. At Google Cloud, we provide a cloud native, highly scalable and secure, data lakehouse solution that delivers choice and interoperability to customers. Our cloud native architecture reduces cost and improves efficiency for organizations.  Our solution is based on:Storage: Providing choice of storage across low cost object storage in Google Cloud Storage or highly optimized analytical storage in BigQueryCompute: Serverless compute that provide different engines for different workloadsBigQuery, our serverless cloud data warehouse provides ANSI SQL compatible engine that can enable analytics on petabytes of data.Dataproc, our managed Hadoop and Spark service enables using various open source frameworksServerless Spark, allows customers to submit their workloads to a managed service and take care of the job execution. Vertex AI, our unified MLOps platform enables building large scale ML models with very limited codingAdditionally you can use many of our partner products like Databricks, Starburst or Elastic for various workloads.Management: Dataplex enables a metadata-led data management fabric across data in Google Cloud Storage (object storage) and BigQuery (highly optimized analytical storage). Organizations can create, manage, secure, organize and analyze data in the lakehouse using Dataplex.Let’s take a closer look at some key characteristics of a data lakehouse architecture and how customers have been building this on GCP at scale. Storage OptionalityAt Google Cloud our core principle is delivering an open platform. We want to provide customers with a choice of storing their data in low cost object storage in Google Cloud Storage or highly optimized analytical storage or other storage options available on GCP. We recommend organizations store their structured data in BigQuery Storage. BigQuery Storage also provides a streaming API that enables organizations to ingest large amounts of data in real-time and analyze it. We recommend unstructured data to be stored in Google Cloud storage. In some cases where organizations need to access their structured data in OSS formats like Parquet or ORC they can store them on Google Cloud Storage. At Google Cloud we have invested in building Data Lake Storage API also known as BigQuery Storage API to provide consistent capabilities for structured data across both BigQuery and GCS storage tiers. This API enables users to access BigQuery Storage and GCS through any open source engine like Spark, Flink etc. Storage API enables users to apply fine grained access control on data in BigQuery and GCS storage (coming soon).Serverless ComputeThe data lakehouse enables organizations to break data silos and centralize data, which facilitates various different types of use cases across organizations. To get maximum value from data, Google Cloud allows organizations to use different execution engines, optimized for different workloads and personas to run on top the same data tiers. This is made possible because of complete separation of compute and storage on Google Cloud.  Meeting users at their level of data access including SQL, Python, or more GUI-based methods mean that technological skills do not limit their ability to use data for any job. Data scientists may be working outside traditional SQL-based or BI types of tools. Because BigQuery has the storage API, tools such as AI notebooks, Spark running on Dataproc, or Spark Serverless can easily be integrated into the workflow. The paradigm shift here is that the data lakehouse architecture supports bringing the compute to the data rather than moving the data around. With serverless Spark and BigQuery, data engineers can spend all their time on the code and logic. They do not need to manage clusters or tune infrastructure. They submit SQL or PySpark jobs from their interface of choice, and processing is auto-scaled to match the needs of the job.BigQuery leverages serverless architecture to enable organizations to run large scale analytics using a familiar SQL interface. Organizations can leverage BigQuery SQL to run analytics on petabyte scale data sets. In addition, BigQuery ML democratizes machine learning by letting SQL practitioners build models using existing SQL tools and skills. BigQuery ML is another example of how customers’ development speed can be increased by using familiar dialects and the need to move data.  Dataproc, Google Cloud’s managed Hadoop, can read the data directly from lakehouse storage; BigQuery or GCS and run its computations, and write it back. In effect, users are given freedom to choose where and how to store the data and how to process it depending on their needs and skills. Dataproc enables organizations to leverage all major OSS engines like Spark, Flink, Presto, Hive etc.  Vertex AI is a managed machine learning (ML) platform that allows companies to accelerate the deployment and maintenance of artificial intelligence (AI) models. Vertex AI natively integrates with BigQuery Storage and GCS to process both structured and unstructured data. It enables data scientists and ML engineers across all levels of expertise to implement Machine Learning Operations (MLOps) and thus efficiently build and manage ML projects throughout the entire development lifecycle. Intelligent data management and governanceThe data lakehouse works to store the data in a single-source-of-truth, making minimal copies of the data. Consistent security and governance is key to any lakehouse. Dataplex, our intelligent data fabric service, provides data governance and security capabilities across various lakehouse storage tiers built on GCS and BigQuery. Dataplex uses metadata associated with the underlying data to enable organizations to logically organize their data assets into lakes and data zones. This logical organization can span across data stored in BigQuery and GCS. Dataplex sits on top of the entire data stack to unify governance and data management. It provides a unified data fabric that enables enterprises to intelligently  curate,secure and govern data, at scale, with an integrated analytics experience. It provides automatic data discovery and schema inference across different systems and complements this with automatic registration of metadata as tables and filesets into metastores. With built-in data classification and data quality checks in Dataplex, customers have access to data they can trust.Data sharing: is one of the key promises of evolved data lakes is that different teams and different personas can share the data across the organization in a  timely manner. To make this a reality and break organizational barriers, Google offers a layer on top of BigQuery called Analytics Hub. Analytics Hub provides the ability to create private data exchanges, in which exchange administrators (a.k.a. data curators) give permissions to publish and subscribe to data in the exchange to specific individuals or groups both inside the company and externally to business partners or buyers. (within or outside of their organization). Open and flexibleIn the ever evolving world of data architectures and ecosystems, there are a growing suite of tools being offered to enable data management, governance, scalability, and even machine learning. With promises of digital transformation and evolution, organizations often find themselves with sophisticated solutions that have a significant amount of bolted-on functionality. However, the ultimate goal should be to simplify the underlying infrastructure,and enable teams to focus on their core responsibilities: data engineers make raw data more useful to the organization, data scientists explore the data and produce predictive models so business users can make the right decision for their domains.Google Cloud has taken an approach anchored on openness, choice and simplicity and offers a planet-scale analytics platform that brings together two of the core tenants of enterprise data operations, data lakes and data warehouses into a unified data ecosystem.  The data lakehouse is a culmination of this architectural effort and we look forward to working with you to enable it at your organization.
