Klima: Schwärzer als Kohle

Holz zu verbrennen gilt als umweltfreundlich. Doch um den Holzbedarf all der Kamine und Biomassekraftwerke zu stillen, werden ganze Wälder vernichtet. Zudem entstehen bei der Verfeuerung enorm viel CO2 und Feinstaub. Ein Bericht von Daniel Hautmann (Umweltschutz, Erneuerbare Energien)

Modernize Enterprise Networking with Cisco SD-WAN and Google Cloud

Enterprises are increasingly adopting hybrid and multi-cloud to deliver the best experiences for their customers. The network is at the foundation of this transformation, but is getting exponentially more complex to manage, secure, and scale throughout an enterprise footprint that can include multiple clouds, SaaS applications, on-prem locations, and geographies.To help enterprise customers with these modern network challenges, we are expanding our partnership with Cisco to bring the best of both Cisco and Google Cloud technologies together, with a new turnkey networking solution: Cisco SD-WAN Cloud Hub with Google Cloud.With tighter integrations between Cisco and Google Cloud, this solution will bring an end-to-end network that adapts to application needs, and that enables secure and on-demand connectivity from a customer’s branch, to the edge of the cloud, through Google Cloud’s backbone, and to applications running in Google Cloud, a private data center, another cloud or a SaaS application.Google Cloud provides industry-leading hybrid and multi-cloud services, robust connectivity, and security solutions. We have developed technologies that give our customers the freedom to develop, deploy, and secure applications anywhere—including Anthos, which simplifies hybrid and multi-cloud deployments. The network that supports services like YouTube, Search, Maps and Gmail is the same infrastructure that provides connectivity to our Google Cloud customers and their users. It consists of a system of high-capacity fiber optic cables across the globe and peers with 3,000 internet service providers (ISPs) in 200+ countries and territories for “last mile” delivery. Our network is also completely software defined, which allows us to consistently select the best egress point to optimize performance and availability.Many customers rely on Cisco technologies to build and manage their enterprise networks. Cisco SD-WAN is an industry leading solution that provides enterprises with a single pane of glass to manage their entire WAN network, optimizes and secures connectivity between enterprise footprints, and simplifies IT operations by automating routine tasks. We believe by combining the core technology strengths of both Cisco and Google Cloud, we can provide best-in-class, cloud-delivered enterprise networking solutions that make network management easy for our customers and allow them to meet their business needs with agility.As Sachin Gupta, SVP, Product, Intent-Based Networking Group at Cisco said, “Cisco’s SD-WAN solution provides end-to-end automation, security, observability and application experience between users anywhere and a hybrid, multi-cloud environment. Cisco SD-WAN Cloud Hub will enable customers to seamlessly extend intent and policy to enterprise applications running natively in Google Cloud.”Cisco SD-WAN Cloud Hub with Google Cloud will bring a new set of capabilities to our customers to simplify enterprise networking and advance security capabilities, while helping IT teams minimize operational costs and meet application service-level objectives (SLOs):A flexible, on-demand network that allows customers to automatically provision a reliable, global network that grows with enterprises’ business needs. In most cases, customer traffic enters Google’s network directly from their last mile provider and stays on Google’s network while it traverses the globe. Combining Cisco’s advanced SD-WAN capabilities with Google’s software-defined backbone, customers get an end-to-end network that not only optimizes connectivity between branches, stores and to the cloud, but also provides telemetry for troubleshooting and diagnostic purposes. Automated application and path-aware routing takes the complexity out of mapping business services to the appropriate network. The Cisco SD-WAN Cloud Hub with Google Cloud solution allows customers to publish all of their services in a single place with the ability to define the intent of how the network should treat those services in an automated fashion, reducing time to onboard new services on to the network. With a combined view of network telemetry, this solution also provides the most optimized path to interconnect Anthos-based services hosted in hybrid/multi cloud environments. Stronger, smarter security thanks to Cisco SD-WAN Cloud Hub with Google Cloud’s end-to-end security, which seamlessly integrates network control and available application-layer security controls based on workload and user identities. With this rich set of controls, customers get security at multiple layers, resulting in stronger protection for their applications.WWT, the global technology and solutions provider, and a global strategic partner of both Google Cloud and Cisco, sees strong opportunities for businesses to accelerate their customers’ digital transformations with the Cisco SD-WAN Cloud Hub with Google Cloud.“Customers are looking at modernizing their network along with moving and containerizing applications with technologies like Google Cloud’s Anthos and placing those workloads in Multicloud Architectures,” said Derrick Monahan, WWT Cloud Networking Architect. “Due to the fluid nature of the where data, applications, and services reside, along with a need for a more integrated security strategy, Cisco SD-WAN Cloud Hub with Google Cloud Platform will be a key architectural step to accelerating our customers Digital Strategy.”Cisco and Google Cloud intend to invite select customers to participate in previews of this solution by the end of 2020. General availability is planned for the first half of 2021. To learn more, read Cisco’s blog and visit our partnership website.

Back up on demand, emulate and develop with ease — new Spanner features

At Google, we built Cloud Spanner to support our need for a scalable, multi-version database with relational semantics. It’s become an important capability for teams that need a globally distributed, strongly consistent database service. Spanner continues to launch new enterprise capabilities, and we’re announcing the general availability of managed backup-restore. This can help you achieve high business continuity and add data protection without much management overhead. This feature provides you protection against user or application errors that result in logical data corruption. You can now take consistent, on-demand backup of databases in your regional or multi-regional configurations, and restore those backups onto the same or different instance with the same instance configuration. These restores are optimized to reduce the time to first byte access to the data in a backup. This means you can get access to terabytes of data being restored from a backup within minutes after a failure. Life sciences and healthcare organization Verily, an Alphabet company, launched the Project Baseline COVID-19 Testing Program to expand access to COVID-19 screening and testing. Verily is using Spanner to ensure the Project Baseline application is able to scale automatically to meet the demand and provide high availability. In addition to scale insurance, Spanner offers strong external consistency with a monthly uptime SLA of up to 99.999%. Google Cloud customers across industries, including financial services, retail, gaming and technology, use Spanner for workloads that must be able to scale quickly while not compromising on relational semantics, atomic transactions, and strong external consistency.This new managed backup-restore capability is available via client libraries, API, gcloud, and Cloud Console. You can use this feature to back up and restore your databases, whatever their size. Here’s what it looks like in practice:We’re also introducing new features to add even more reliability, flexibility, and ease of use to your experience developing applications with Spanner, including:Local emulator (in beta)Cloud Spanner Emulator can be used for correctness testing. Spanner Emulator runs in an offline environment and provides emulation of the Spanner API (both REST and gRPC) and SQL layer. It helps reduce application development costs and improve developer productivity. Query optimizer versioning (generally available)Spanner’s optimizer uses a combination of well-established heuristics and cost-based optimization to produce efficient plans for low-latency queries with optimal CPU utilization. Newly released Query Optimizer versions let Spanner generate even more efficient query execution plans. However, for a small subset of queries, this can result in varying performance profiles. With Query Optimizer versioning, you now have greater control and can run your database, application, and queries with specific optimizer versions that produce the best performance, and switch between the new version or prior versions at your convenience. Foreign keys (generally available)Foreign keys in Spanner allow you to define referential integrity constraints between columns in different tables. Spanner ensures referential integrity by rejecting attempts to add invalid data. The addition of foreign key support means Spanner now has two ways to relate table data: foreign keys and interleaving. Interleaving also provides referential integrity constraints, but it’s useful primarily in cases where physical co-location of data between parent-child tables can improve query performance.  C++ client library (generally available) If you use C++ for your application development, whether for building games, financial services, or any other high-performance need, you can now benefit from the idiomatic C++ client library for Spanner. This library implements best practices such as session pool management and retry logic so application developers don’t have to worry about those tasks.Learn moreTo get started with Spanner, create an instance or try it out with a Spanner Qwiklab.
