Hyper-Convergence Delivers the Best of Cloud and On-Premises Infrastructure | Rahi

Although organizations are moving more applications and services into the cloud, certain workloads still require the control, reliability and security of on-premises infrastructure. Hyper-convergence has emerged as a key technology for effectively balancing cloud and on-premises resources.

Hyper-converged systems reduce the cost and complexity of on-premises infrastructure by tightly integrating core infrastructure resources into a single platform running on industry-standard hardware. They also provide the foundation for private cloud platforms that deliver some of the speed and scalability of the public cloud, but with greater security and control.

Private clouds offer a compelling mix of scalability and security, but they are notoriously difficult and expensive to implement correctly. It involves properly integrating virtualization, compute, storage and networking components, along with security, management and orchestration functionality. In 2015, a Gartner survey found that roughly 95 percent of private cloud initiatives failed.

Hyper-converged platforms remove many of those challenges through the pre-integration of compute, storage and networking. Combined with a native hypervisor, these resources enable cloud-like levels of automation, scalability, agility and flexibility — but with lower costs, better application performance and better security.

IDC analysts say that IT departments are increasingly adopting hyper-converged systems for the express purpose of building private clouds. The research firm says that the hyper-converged infrastructure market is growing faster than 150 percent a year, and could be worth $6.4 billion by 2020.

Hyper-convergence has evolved from the converged infrastructures developed in recent years to remedy data center bloat. Converged infrastructures consist of pre-racked and cabled compute, storage and networking components integrated into a unified system based upon a validated reference architecture. This approach shortens deployment time, improves management and delivers one-throat-to-choke support.

There are drawbacks, however. Converged infrastructure solutions are made up of distinct hardware components that have been engineered to work together, which can lead to issues with vendor lock-in. In addition, most converged infrastructure products come in standard form factors with rigid configuration rules, severely limiting provisioning and expansion options.

Hyper-converged systems, in contrast, cannot be separated into their component parts. Software-defined technology delivers both compute and storage functions using the same x86 server resources. There’s just one, highly automated platform to manage. However, a key feature of hyper-convergence is its scale-out architecture, which makes it possible to increase capacity by adding modules. This design approach creates a more agile and efficient IT infrastructure for organizations seeking to implement a private cloud.

In fact, hyper-converged systems share several of the characteristics of the cloud, including:

Elasticity.     Hyper-converged systems can be scaled up or down as needed without complex configuration and integration and at low incremental cost.

On-Demand Services. The software-defined approach abstracts compute and storage resources, making it possible automate provisioning.

Resource Pooling. The scale-out architecture of hyper-converged systems creates one logical pool of resources using software that automatically discovers nodes.

Traditionally, IT infrastructure has been designed, configured and implemented on a box-by-box basis, creating a complex, siloed environment that is inflexible and difficult to scale. The cloud provides greater agility but is not suitable for all workloads. Hyper-convergence enables organizations to gain cloud-like simplicity without sacrificing the security and reliability of on-premises infrastructure.

Microsoft windows server 2019 datacenter for inexpensive local storage

From an administration point of view, users can take advantage of the new opportunities that the Microsoft windows server 2019 datacenter offers. The Microsoft windows server 2019 datacenter, which was released in 2018 with a solid foundation, is the successor to Windows Server 2016. Whether it is the security and storage potential or the hybrid cloud environment, you can call this launch from Microsoft one of the best for unleashing more potential for Microsoft Windows Server 2019 data center users.

Widest range of functions

Now, you should know about all three editions here, like the data center, standard, and Microsoft windows server 2019 essentials. The name itself denotes that these are meant to serve different sizes of organizations accordingly. You can choose between the essentials, standard, and data center options depending on your data center requirements and virtualization needs. If the infrastructure is smaller, then the essentials would fit perfectly. However, if you are looking to get the widest range of functions, then the best option would just be the Microsoft windows server 2019 datacenter.

Core characteristics

Understanding the needs that these are meant to satisfy will require you to learn about the core characteristics of all three. So, if you are looking for a cheap data protection choice that is simple and powerful, here are some interesting facts for you. You can construct as many virtual machines as you like, including one Hyper-V host for each license. As previously stated, the Datacenter version allows for a limitless number of Windows and Hyper-V containers. There are some additional perks offered that aren't accessible in any other version of Windows Server. For home business owners and small industries Microsoft access 2016 can be a perfect option.

Network controller

To summarize, the primary distinction seen between the Essential and Standard versions is the number of people and devices supported. The Datacenter edition is designed to meet the requirements of public cloud computing data centers and virtual servers. It provides the capabilities of Windows Server 2019 Standard while being unrestricted. The network controller is a function that is only available in Windows Server Datacenter.

Centralized infrastructure administration

It enables centralized infrastructure administration and provides mechanisms for automatically detecting, setting, and debugging your virtual network configuration. Rather than setting network services and devices individually, a network controller may be used to streamline configuration settings. The Host Guardian Hyper-V Support is yet another functionality that is only accessible in the Datacenter edition.

It's worth mentioning that the Datacenter version includes features for constructing a hyper-converged architecture. For the time being, it is regarded to be one of the most outlay and versatile alternatives for establishing a software-defined computing infrastructure. In essence, the capability of a hyper-converged infrastructure enables you to integrate computing, storage, and networking devices into a cluster center, which leads to better performance while also saving money.

Kuber Notes version 1.9

The competitive environment of today's fast-paced technological market requires businesses to continuously improvise, discover, and find new ways to innovate and grow. Application modernization is just one of these efforts. Using containers and container orchestration applications is one area that has seen increased interest in recent years. According to estimates, the global application container market was worth approximately $700 million in 2017. However, exports have been projected to be around $8 billion by 2023.

Applications are still lifted and shifted from virtual machines to containers and Dev Ops and information technology professionals will appreciate the same network management agility from SDDCs or software-defined data centers. Here is where a container orchestration tool like kuber Notes comes into the picture to fill the gap. When you want something standard and also available as an open-source framework, this is going to be the best option for you. The kuber Notes version 1.9 is the choice of most of the Dev Ops teams. Also if you are a data scientist or a CAD programmer then windows 10 pro for workstation could be your best bet.

This article intends to cover in detail the installation and configuration of Rook, and how to integrate a highly available Ceph Storage Cluster to an existing kubernetes cluster. I’m performing this process on a recent deployment of Kubernetes in Rocky Linux 8 servers. But it can be used with any other Kubernetes Cluster deployed with Kubeadm or automation tools such as Kubespray and Rancher. In the initial days of Kubernetes, most applications deployed were Stateless meaning there was no need for data persistence. However, as Kubernetes becomes more popular, there was a concern around reliability when scheduling stateful services. Currently, you can use many types of storage volumes including vSphere Volumes, Ceph, AWS Elastic Block Store, Glusterfs, NFS, GCE Persistent Disk among many others. This gives us the comfort of running Stateful services that requires robust storage backend. What is Rook / Ceph? Rook is a free to use and powerful cloud-native open source storage orchestrator for Kubernetes. It provides support for a diverse set of storage solutions to natively integrate with cloud-native environments. More details about the storage solutions currently supported by Rook are captured in the project status section. Ceph is a distributed storage system that provides file, block and object storage and is deployed in large scale production clusters. Rook will enable us to automate deployment, bootstrapping, configuration, scaling and upgrading Ceph Cluster within a Kubernetes environment. Ceph is widely used in an In-House Infrastructure where managed Storage solution is rarely an option. Rook uses Kubernetes primitives to run and manage Software defined storage on Kubernetes. Key components of Rook Storage Orchestrator: Custom resource definitions (CRDs) – Used to create and customize storage clusters. The CRDs are implemented to Kubernetes during its deployment process. Rook Operator for Ceph – It automates the whole configuration of storage components and monitors the cluster to ensure it is healthy and available DaemonSet called rook-discover – It starts a pod running discovery agent on every nodes of your Kubernetes cluster to discover any raw disk devices / partitions that can be used as Ceph OSD disk. Monitoring – Rook enables Ceph Dashboard and provides metrics collectors/exporters and monitoring dashboards Features of Rook Rook enables you to provision block, file, and object storage with multiple storage providers Capability to efficiently distribute and replicate data to minimize potential loss Rook is designed to manage open-source storage technologies – NFS, Ceph, Cassandra Rook is an open source software released under the Apache 2.0 license With Rook you can hyper-scale or hyper-converge your storage clusters within Kubernetes environment Rook allows System Administrators to easily enable elastic storage in your datacenter By adopting rook as your storage orchestrator you are able to optimize workloads on commodity hardware Deploy Rook & Ceph Storage on Kubernetes Cluster These are the minimal setup requirements for the deployment of Rook and Ceph Storage on Kubernetes Cluster. A Cluster with minimum of three nodes Available raw disk devices (with no partitions or formatted filesystems) Or Raw partitions (without formatted filesystem) Or Persistent Volumes available from a storage class in block mode Step 1: Add Raw devices/partitions to nodes that will be used by Rook List all the nodes in your Kubernetes Cluster and decide which ones will be used in building Ceph Storage Cluster. I recommend you use worker nodes and not the control plane machines.

This should be done on a machine with kubeconfig configured and confirmed to be working. You can also clone Rook’s specific branch as in release tag, for example: cd ~/ git clone --single-branch --branch release-1.8 https://github.com/rook/rook.git All nodes with available raw devices will be used for the Ceph cluster. As stated earlier, at least three nodes are required cd rook/deploy/examples/ Deploy the Rook Operator The first step when performing the deployment of deploy Rook operator is to use. Create required CRDs as specified in crds.yaml manifest: [root@k8s-bastion ceph]# kubectl create -f crds.yaml customresourcedefinition.apiextensions.k8s.io/cephblockpools.ceph.rook.io created customresourcedefinition.apiextensions.k8s.io/cephclients.ceph.rook.io created customresourcedefinition.apiextensions.k8s.io/cephclusters.ceph.rook.io created customresourcedefinition.apiextensions.k8s.io/cephfilesystemmirrors.ceph.rook.io created

Let’s set default namespace to rook-ceph: # kubectl config set-context --current --namespace rook-ceph Context "kubernetes-admin@kubernetes" modified. Considering that Rook Ceph clusters can discover raw partitions by itself, it is okay to use the default cluster deployment manifest file without any modifications. [root@k8s-bastion ceph]# kubectl create -f cluster.yaml cephcluster.ceph.rook.io/rook-ceph created For any further customizations on Ceph Cluster check Ceph Cluster CRD documentation. When not using all the nodes you can expicitly define the nodes and raw devices to be used as seen in example below: storage: # cluster level storage configuration and selection useAllNodes: false useAllDevices: false nodes: - name: "k8snode01.hirebestengineers.com" devices: # specific devices to use for storage can be specified for each node - name: "sdb" - name: "k8snode03.hirebestengineers.com" devices: - name: "sdb" To view all resources created run the following command: kubectl get all -n rook-ceph Watching Pods creation in rook-ceph namespace: [root@k8s-bastion ceph]# kubectl get pods -n rook-ceph -w This is a list of Pods running in the namespace after a successful deployment: [root@k8s-bastion ceph]# kubectl get pods -n rook-ceph NAME READY STATUS RESTARTS AGE

Step 4: Deploy Rook Ceph toolbox in Kubernetes TheRook Ceph toolbox is a container with common tools used for rook debugging and testing. The toolbox is based on CentOS and any additional tools can be easily installed via yum. We will start a toolbox pod in an Interactive mode for us to connect and execute Ceph commands from a shell. Change to ceph directory: cd ~/ cd rook/deploy/examples Apply the toolbox.yaml manifest file to create toolbox pod: [root@k8s-bastion ceph]# kubectl apply -f toolbox.yaml deployment.apps/rook-ceph-tools created Connect to the pod using kubectl command with exec option: [root@k8s-bastion ~]# kubectl -n rook-ceph exec -it deploy/rook-ceph-tools -- bash [root@rook-ceph-tools-96c99fbf-qb9cj /]# Check Ceph Storage Cluster Status.

Cephfs Cephfs is used to enable shared filesystem which can be mounted with read/write permission from multiple pods.

A list of businesses that have used cloud computing as a business model

Digital transformation is increasingly being driven by the cloud. Many businesses, like as Netflix and Amazon, are built on this basis, and it is now a crucial part of any company's entire strategy. The cloud, on the other hand, raises a number of questions about its safety and privacy. It is fortunate that these problems may be addressed without the need for a third party. While cloud computing is a fantastic tool for organizations, it can also be rather costly to implement and keep running smoothly.

As per John Lopinto Cloud services are being offered by a growing number of businesses. Cloud computing giants like Google Cloud and Microsoft Azure are just a few examples. However, there are many more out there who are discovering methods to keep up with the pack. Hyper-converged infrastructure is a focus for CenturyLink, and it is also a prominent supplier of disaster recovery as a service, making it an even more well-known brand in the cloud market. Despite the fact that Nutanix is not an IaaS provider, the company has found a place in the cloud sector.

John Lopinto stated that Among Oracle's cloud infrastructure investments are the servers and networking equipment that power such infrastructures. Aside from SaaS, Oracle has aspirations to compete in other sectors such as enterprise resource planning (ERP). Through its NetSuite clouds, it also provides services in human resource management, supply chain management, and sales and marketing. With such a large internet market, Cisco is also making significant investments in cloud computing. Using SAP's HANA cloud computing technology, which is supposed to be the next big thing,

A major participant in Asia, Alibaba is also one of China's main cloud providers. It's a cloud market leader in China, and its sales pitch is effective. Despite this, despite its worldwide reach, Alibaba does not dominate the North American market. But it is still a key participant in the industry despite having a lesser market share than Amazon Web Services. Choosing a cloud computing provider should be done with caution, since they may not be dependable or give enough assistance.

Some of the biggest brands in the cloud computing industry are AWS, Amazon, and Microsoft. Because of this, Alibaba is now the third-largest cloud provider in the world. Alibaba, Google, Oracle, and Amazon are the other big players in the cloud, although there is a lot of rivalry amongst them. However, cloud computing has several benefits for organizations on the rise. Check through customer reviews and price alternatives to figure out which firm best suits your needs.

Microsoft Azure is another prominent cloud service. One of the most successful and lucrative cloud providers in the world is a direct rival to Amazon. Its greatest asset is its long history with the company. Enterprise software has long relied on Microsoft's Windows operating system and Microsoft Office apps. In addition, Azure offers the greatest degree of security and regulatory compliance available anywhere. Your company's agility and competitiveness will be enhanced by using it.

Besides Alibaba, there are other cloud computing providers in the United States that are having an effect. When it comes to power computing, Alibaba, the Chinese counterpart of Amazon, is growing. In the meanwhile, cloud platforms and technology services are responsible for roughly half of Oracle and IBM's income. IBM's cloud platforms and technology services accounted for over half of its total revenue in 2016. Small and medium-sized businesses are more sensitive to disruption whereas the giant enterprises are focused on gaining market share.

Cloud computing is gaining traction not just in China, but throughout the world as well. Companies may utilize another location's server without having to worry about the infrastructure while using this service. As a result, businesses are better able to meet the changing demands of their clients. By outsourcing their cloud-based services, these organizations may save money on IT. Pay just for what you use, whenever you need it. Risks exist, and the expense of security is the largest issue.

John Lopinto included that despite the fact that many businesses have already moved to the cloud, the industry is still mostly controlled by huge corporations like Microsoft, Google, and Amazon. Even if a small number of enterprises can replicate Amazon's offering, others would be left behind. The final say rests with you. Compare the advantages and disadvantages of each service you're considering. Cloud computing is the way to go if you want to get the most bang for your buck.

New Top Features of Windows Server 2016 | Digital Software Market

Get your Microsoft Windows server 2016 at a discounted price from Digital Software Market. Avail of huge discounts on the state-of-the-art software, visit the website to know more...

This blog will help you discover new features of Microsoft windows server 2016. The features listed above are the ones that are mostly going to have an impact on your work.

Nano Server-

Windows Server 2016  has now come up with an updated Nano Server module for building Nano Server images along with more separation of physical host and guest virtual machine functionality. You also get an improved Recovery Console and inbound and outbound firewall including the ability to repair the configuration of WinRMin in addition to that. 

Nano instances consume less than 512MB of disk space and less than 256MB of memory, depending on the configuration. This makes a big difference for all virtual machines built on Nano, acting as an infrastructure host installed on bare metal and as a guest operating system running as a virtual machine. New in Technical Preview 3 is the Emergency Management Console, which allows you to view and fix network issues directly from the Nano Server Console.

Hyper-V rolling upgrades-

Upgrading to a new operating system gives out significant challenges in many respects. Earlier versions of Windows Server did not allow you to upgrade without stopping the cluster. This can be a serious problem for production systems that normally run continuously. In many cases, the workaround was to launch a new cluster running the updated operating system and then migrate the workload from the old cluster. Of course, this required entirely new hardware. Microsoft Windows Server 2016 supports the rolling cluster upgrades from previous Windows Server 2012 R2. This means you can perform these upgrades without stopping your cluster or migrating to new hardware. This process is similar in that all active roles on individual nodes in the cluster must be moved or removed to another node in order to upgrade the host operating system. The difference is that all members of the cluster continue to operate at the Windows Server 2012 R2 functional level (upgraded from the old host) until all hosts run the new operating system and explicitly upgrade the cluster's functional level. 

PowerShell Updates-

PowerShell keeps receiving updates with each new release of the operating system. Windows Server 2016 displays several new PowerShell cmdlets that focus on specific features. You can also use PowerShell commands to see the differences between new releases. The PowerShell cmdlet Get-Command returns a list of commands that you can send to a file for further processing.

The new cmdlets covered include 21 DNS-related commands, 11 Windows Defender, 36 Hyper-V, 17 IIS management, and 141 network controller-related commands. Another major driving force for PowerShell in this release is related to the Desired State Configuration (DSC). Microsoft has done a lot of work to make DSC the first tool to configure and maintain not only Windows Server, but also Linux servers. With the introduction of the new package manager service, OneGet, there are many new possibilities driven by PowerShell.

Networking Enhancements- 

Convergence is a buzzword here, with new features that help businesses and hosting providers merge traffic from multiple tenants to reduce the number of network interfaces. This may reduce the number of network ports required by half. Another new feature is called Packet Direct. It focuses on increasing the efficiency of the entire workload and including everything from small packets to large data transfers. 

Technical Preview 3 includes a new server role called Network Controller. It provides a central point for monitoring and managing network infrastructure and services. Other extensions that support software-defined network capabilities include an L4 load balancer, an extended gateway for connecting to Azure and other remote sites, and an integrated network fabric that supports both RDMA and tenant traffic.

Storage Spaces Direct-

Windows Server 2016 Technical Preview 2 takes the storage space one step further and has the ability to build a highly available storage system using only the disks directly attached to each node. Restoring force between nodes uses the network and the SMB3 protocol. This new feature, called Storage Spaces Direct, continues to support older SATA-based hardware while leveraging newer hardware such as NVMe SSDs. At least four nodes must be available to create a cluster using Storage Spaces Direct.

ReFS as a Primary File System-

The Resilient File System (ReFS) is another feature introduced in Windows 8 and Windows Server 2012. ReFS was designed from the beginning to be more resistant to corruption than previous versions and bring many advantages to the NTFS on-disk format. Microsoft has enhanced both the usefulness and importance of ReFS in Windows Server 2016 TP2 by making the file system suitable for Hyper-V workloads. 

This has a significant impact on Hyper-V performance. To get started, you should see a new virtual machine with a fixed size VHDX created about as fast as pressing return. The same benefits apply to creating checkpoint files and merging VHDX files created during backup creation. These features are similar to what ODX (Offload Data Transfers) can perform on large storage appliances.
