All things cloud are major topics of conversation at the VMworld user conference next week, ratcheded up a notch by VMware's $4.8 billion plans to acquire cloud development firm Pivotal and security provider Carbon Black.\nVMware said during its quarterly financial call this week it would spend about $2.7 billion on Pivotal and its Cloud Foundry hybrid cloud development technology, and about $2.1 billion for the security technology of Carbon Black, which includes its Predictive Security Cloud and other endpoint-security software.\u00a0 Both amounts represent the enterprise value of the deals the actual purchase prices will vary, experts said.\n\nVMware has deep relationships with both companies. Carbon Black technology is part of VMware\u2019s AppDefense endpoint security. Pivotal has a deeper relationship in that VMware and Dell, VMware\u2019s parent company, spun out Pivotal in 2013.\n\u201cThese acquisitions address two critical technology priorities of all businesses today\u00a0\u2013 building modern, enterprise-grade applications and protecting enterprise workloads and clients. With these actions we meaningfully accelerate our subscription and SaaS offerings and expand our ability to enable our customers\u2019 digital transformation,\u201d said VMware CEO Pat Gelsinger, on the call.\nWith regards to the Pivotal acquisition Gelsinger said the time was right to own the whole compute stack. \u201cWe will now be uniquely positioned to help customers build, run and manage their cloud environment, and customers can go one place to get all of this technology,\u201d Gelsinger said. \u201cWe embed the technology in our core VMware platform, and we will explain more about that at VMworld next week.\u201d\nOn the Carbon Black buy Gelsinger said he expects the technology to be integrated across VMware\u2019s produce families such as NSX networking software and vSphere, VMware's flagship virtualization platform.\n\u201cSecurity is broken and fundamentally customers want a different answer in the security space. We think this move will be an opportunity for major disruption.\u201d\nPatric Morley, president and CEO of Carbon Black wrote of the deal: \u201cVMware has a vision to create a modern security platform for any app, running on any cloud, delivered to any device \u2013 essentially, to build security into the fabric of the compute stack. Carbon Black\u2019s cloud-native platform, our ability to see and stop attackers by leveraging the power of our rich data and behavioral analytics, and our deep cybersecurity expertise are all truly differentiating.\u201d\nBoth transactions are expected to close in the second half of VMware\u2019s fiscal year, which ends Jan. 31. \nVMware has been on a massive buying spree this year that has included:\n\nAvi Networks for multi-cloud application delivery services.\nBitfusion for hardware virtualization.\nUhana, a company that is employing deep learning and real-time AI in carrier networks and applications, to automate network operations and optimize application experience.\nVeriflow, for network verification, assurance, and troubleshooting.\nHeptio for its Kubernetes technology.\n\nKubernetes integration will be a big topic at VMworld, Gelsinger hinted. \u201cYou will hear very specific announcements about how Heptio will be used. [And] we will be announcing major expansions of our Kubernetes and modern apps portfolio and help Pivotal complete that strategy. Together with Heptio and Pivotal, VMware will offer a comprehensive Kubernetes-based portfolio to build, run and manage modern applications on any cloud,\u201d Gelsinger said.\n\u201cVMware has increased its Kubernetes-related investments over the past year with the acquisition of Heptio to become a top-three contributor to Kubernetes, and at VMworld we will describe a major R&D effort to evolve VMware vSphere into a native Kubernetes platform for VMs and containers.\u201d\nOther updates about where VMware vSphere and NSX-T are headed will also be hot topics.\nIntroduced in 2017, NSX-T Data Center software is targeted at organizations looking to support multivendor cloud-native applications, bare-metal workloads, hypervisor environments and the growing hybrid and multi-cloud worlds. In February the company anointed NSX-T the company\u2019s go-to platform for future software-defined cloud developments.\nVMware is battling Cisco's Application Centric Infrastructure, Juniper's Contrail system and other platforms from vendors including Pluribus, Arista and Big Switch. How NSX-T evolves will be key to how well VMware competes.\nThe most recent news around vSphere was that new features of its Hybrid Cloud Extension application-mobility software enables non-vSphere as well as increased on-premises application workloads to migrate to a variety of specific cloud services. Introduced in 2017, VMware HCX lets vSphere customers tie on-premises systems and applications to cloud services.\nThe HCX announcement was part of VMware\u2019s continued evolution into cloud technologies. In July the company teamed with Google to natively support VMware workloads in its Google Cloud service, giving customers more options for deploying enterprise applications.\nFurther news about that relationship is likely at VMworld as well.\nVMware also has a hybrid cloud partnership with Microsoft\u2019s Azure cloud service. \u00a0That package, called Azure VMware Solutions is built on VMware Cloud Foundation, which\u00a0 is a packag of vSphere with NSX network-virtualization and VSAN software-defined storage-area-network platform. The company is expected to update developments with that platform as well.
