These days, data could be stored anywhere, in any environment. It’s spread across
on-premises and offsite locations, public and private clouds, pure and hybrid
installations. Data Center have gotten more complex, and management is more siloed. At
the same time, IT organizations are expected to maintain everything flawlessly,
delivering high availability and security across globally distributed infrastructure
with disparate toolsets. This is the challenge of Hybrid Data Centers.
The modern, Hybrid Data Center enables greater IT efficiency, automation, and agility,
supporting the delivery of new application workloads across dynamic network fabric and
virtual machine infrastructure. Use of a hybrid data center is an evolution strategy
that allows organizations to create the right mix of cloud and traditional IT to suit
their needs.
GREENNET offer assessment, design and support of data center & cloud solutions focusing
on operational stability, scalability, agility and cost efficiency. Our data center and
cloud experts can work with you to determine your readiness and uncover the
opportunities and define the results your company can achieve by implementing private,
public or hybrid cloud infrastructures.
Public clouds offer an incredible breadth of features and services and elastic capacity
that allows for rapid application development. Public clouds also offer cost savings, as
enterprises must pay only for the resources they consume, and public clouds can scale
easily to ensure high availability.
On the other hand, private clouds excel in situations where low latency is critical, or
where data sovereignty regulations necessitate specific location requirements. Private
clouds can also offer cost savings on operations where capacity consumption is
predictable, and many organizations prefer that certain workloads be kept on-premises
because of policy, security or compliance requirements.
As the capabilities of public and private clouds continue to evolve, application and
data portability enable enterprises to continually choose the best cloud resource for a
given workload. But to ensure seamless portability and the cohesive use of resources,
organizations need a cloud platform that can deliver consistency across all
environments, providing a common set of tools for managing policies, security,
compliance and optimization.
Enterprise need to adopt a holistic network infrastructure strategy to cope with the
unique performance, security, and management challenges of highly distributed
applications, data, users, and devices. Legacy approaches that have relied on manual
processes to secure data and applications and control access to them are no longer
adequate or sustainable.
The networking industry has recognized these challenges and is addressing them in the
form of an intent-based architectural approach that builds on software-defined
networking to allow continuous, dynamic network alignment with IT and business policies.
This means that application, security, and compliance policies can be defined once and
enforced and monitored between any groups of users or things and any application or
service – or even between application and services themselves – wherever they are
located.
In Hybrid cloud environment it is becoming more and more challenging to maintain a
homogeneous enterprise operational model, comply with corporate security policies, and
gain visibility across hybrid environments. Cisco Cloud ACI is a comprehensive solution
that provides simplified operations, consistent policy management and visibility across
multiple on-premises data centers and public clouds or hybrid cloud environments. Cisco
Cloud ACI allows customers running Cisco ACI in their on-premises data centers to extend
their Cisco ACI policies to public clouds.
Large service provides are also deploying VXLAN EVPN open standard based fabrics. With
the industry moving from Frame Encapsulation (MAC-in-MAC) to Packet Encapsulation
(MAC-in-IP), many vendors embraced VXLAN within its Data Center Switching portfolio to
provide a standards based encapsulation technique. Initially, VXLAN was introduced as a
Layer 2 service only, with simple Flood and Learn semantic as Ethernet. Since VXLAN was
enhanced with own control plane to overcome limitations of VXLAN Flood and Learn.
Multiprotocol Border Gateway Protocol with Ethernet Virtual Private Network (MP-BGP
EVPN) was introduced as the control plane, with VXLAN being used in the data plane.
To automate the provisioning of their networks, service providers implement DevOps
methodologies and GitOps tools for Continuous Integration/ Continuous Delivery (CI/CD)
that is streamlines operations and increases infrastructure agility.
Great demands are placed on a modern server platform. It should not only be reliable and
deliver good performance. It must also be possible to scale up and down in a predictable
way. Integration with networks, storage platforms, virtualization, and other solutions
must be reliable and straightforward. And it must be easy to manage.
A popular way to row all challenges in port is to use a Hyperconverged infrastructure
(HCI) solution. Hyperconverged infrastructure (HCI) combines compute, virtualization,
storage, and networking in a single cluster. Starting with as few as three nodes,
enterprises can easily scale out to match computing and storage resource needs.
Hyperconvergence brings cloudlike simplicity on-premises and within a single, easily
managed platform.
HCI delivers deeper abstraction and higher automation and scalability than converged
infrastructure. HCI simplifies administration by providing a single point of management.
HCI fully integrates with your entire data center, eliminating the need for separate
servers and network storage and delivering on-demand infrastructure for data-centric
workloads.
Enterprises are facing unprecedented challenges storing and managing data. Not only must
they handle greater amounts of data, but they must also work with different types of
data, much of it unstructured. At the same time, workloads have become more complex and
varied and are often distributed across multiple geographic regions.
With the rise of next-generation applications driven by trends like big data and the
Internet of Things, organizations are turning to software-defined storage solutions to
achieve greater agility, resilience, scalability and cost-efficiency. This approach to
storage architecture uses a layer of software to provision, orchestrate and manage
physical data storage capacity on industry-standard servers. By decoupling storage
management software from hardware, software-defined solutions enable hardware and
software to be acquired independently rather than locking organizations into proprietary
platforms.
The key to making software-defined storage work is choosing solutions that are fast to
deploy and simple to manage, that support multiple workloads and a variety of use cases,
and that relieve IT teams of the complexity of managing a heterogeneous collection of
storage media.
