IT as a Service
Moving to an IT-as-a-service model means looking at enterprise infrastructure architecture differently. Rather than organizing your architecture around projects, you need to organize it around relevant business services. It requires a shift from thinking in terms of hard assets to thinking instead of the business needs of customers.
GreenPages helps clients adopt software-defined approaches to virtualize, abstract, and automate data center resources on demand, and build IT catalogs that provide standardized services and hardware configurations tailored to each line of business. With a software-defined infrastructure framework, modern IT organizations can optimize their operations, scale more quickly, and free up valuable administrative time to focus on strategic initiatives.
Software-Defined Networking
GreenPages helps clients implement software-defined networking (SDN) solutions that enable IT to provision and manage network infrastructure more effectively so IT can work on strategic business initiatives while ensuring application availability and user access needs are met.
Software-defined networking greatly increases operational agility by giving IT the ability to shape and control data traffic and create policy driven networks based on automation.
Because SDN is based on software, it allows IT to accelerate service delivery from a centralized virtual network control plane, without regard to where servers or devices are connected. Micro-segmentation is another key feature of SDN that enables a more granular network security inside the perimeter of the datacenter to handle advanced persistent threats and coordinated attacks.
Regardless of which SDN solution you choose, there is a lot of backend work that needs to be done to prepare your environment, including having a deep understanding of your applications and their dependencies. GreenPages helps clients build and implement complex SDN architectures, including Day 2 SDN services to ensure your SDN solution is fully optimized and leveraged for the long run.
Network Function Virtualization
GreenPages helps clients implement NFV solutions to remove bottlenecks caused by manual processes and drive rapid development of new network services with elastic scale and automation. Where SDN uses a control plane to make decisions about network traffic, Network Function Virtualization (NFV) virtualizes all physical network resources and puts them on a commodity server or switch beneath a hypervisor which allows the network to grow without the addition of more devices.
While NFV does add complexity to your network and brings with it possible security challenges (e.g., multi-tenancy and live migration) which make it vulnerable to some cybersecurity attacks, GreenPages helps ensure that your NFV solution is architected to simplify network management and minimize your attack surface.
Intent-based Networking
The biggest benefits from Intent-Based Networking Systems (IBNS) are improving network agility and availability, and supporting unified intent and policy across multiple infrastructures.
GreenPages helps clients design and implement intent-based networking frameworks that use context and analytics to constantly learn and adapt to changing needs and conditions. By creating a model that works in a continuous loop to deliver the outcomes based on business intent, organizations can use intelligence to handle issues automatically without manual intervention.
Intent-based Networking Model
- Activation: Install policies across the physical and virtual infrastructure with networkwide automation.
- Translation: Intent is captured, interpreted, and translated into policies that are also checked for integrity.
- Assurance: Ensures that the intent is honored and maintains validation and verification, while also recommending corrective action.
SD-WAN
As modern organizations increasingly leverage public and private cloud, WAN (Wide Area Network) performance becomes absolutely critical to application delivery. It's no longer just about bandwidth; IT needs dynamic visibility into the applications (including cloud applications) across the WAN to set policies at the application level.
GreenPages helps clients design and deploy powerful Software-Defined Wan (SD-WAN) architectures that meet the needs of digital era companies by providing analytics for network and application visibility, a centralized policy controller, and automated service provisioning. SD-WAN solutions enable IT to identify and set application-specific policies and SLA criteria around attributes such as latency, jitter, and loss, so that users can be isolated in the case of an outage and traffic can be re-routed automatically while ensuring SLAs are met.
Software Defined Storage
GeenPages’ Software-Defined Storage (SDS) solutions help companies enable multi-cloud flexibility, increase operational efficiency, lower the CapEx costs of managing Network Attached Storage and Storage Areas Network environments, and enable IT to deliver IT services to end users more quickly than ever before.
Similar to server virtualization, SDS removes the physical barriers tying data to hardware. By using storage virtualization to control storage through a software layer abstracted from physical storage devices, IT can automate storage management, enable storage pooling, and manage policies for data deduplication, replication, thin provisioning, snapshots, and backup.
