Converged Infrastructure

Converged infrastructure is an approach to IT deployment that integrates compute, storage, networks, & administration to create a flexible pre-configured system that operates as a consolidated unit.  The benefits include decreased cost of deployment, maintenance & operation, along with simplified management. Nexus Open Systems delivers & supports industry-leading converged infrastructure solutions from Oracle which include Oracle Private Cloud Appliance, Exadata Machine, Oracle Database Appliance & Zero Data Loss Recovery appliance.

These offerings enable customers to optimize their existing storage systems, minimise costs & plan their transition to cloud computing.

Data Management & Optimization

Data Warehousing

With exponential Data growth, businesses should be able to analyse, plan & react to changing business conditions with increasing flexibility & agility.  Most organizations have their data in silos which makes it immensely difficult to consolidate & leverage for meaningful business insights.  Nexus Open Systems delivers Oracle’s industry-leading Oracle Autonomous Datawarehouse to meet this growing need.


Enterprise database management systems enable authorized users to share data quickly & effectively across large organizations.  Nexus Open Systems sells licenses & provides support & maintenance services for major relational database systems including Oracle Database, Microsoft SQL Server & My SQL – all of which are optimized for data integrity, ease of access, security, flexibility, & minimal data loss.


Disaster Recovery

Disaster recovery involves replicating entire IT environments including data, systems, networks & applications.  Having a DR plan with the proper infrastructure & processes enables businesses to restore functionality & data in case of a system failure.  Nexus Open Systems is a value-added reseller for world class system & data replication technology solutions from Veeam, Dbvisit & Oracle.

Back up

With the widespread use of digital platforms, businesses are becoming increasingly data-driven, which means that the prevention of data loss is an important part of business continuity & survival.  To reduce the risk of data loss, businesses need to back up files, databases, operating systems, applications & system configurations in a way which minimises hardware costs & safeguards against data breaches.  Nexus Open Systems provides backup solutions that help our clients meet both Recovery Point Objectives (RPO) & Recovery Time Objectives (RTO).  These solutions include software, hardware & cloud-based offerings from Veeam, Oracle & Microsoft.

High Availability

All organizations use a variety of mission-critical ICT platforms which include databases, applications, websites, e-commerce portals, accounting systems etc.  Unplanned & persistent outages of any of these systems can result in loss of revenue, reputation, customer loyalty & productivity.  Businesses should therefore endeavour to achieve business continuity by investing in high availability solutions that provide fully automated failover to a secondary system for 99.99% uptime for their mission-critical systems.  Nexus Open Systems can deploy high availability solutions from global vendors that do just that.

Today most organizations have the benefit of choosing a cloud adoption strategy that is suitable for their business which can be public, hybrid or private cloud solutions.  Nexus Open Systems provides the following types of cloud services from Oracle & Microsoft.

      Infrastructure as a service (IaaS)

      Platform as a service (PaaS)

      Software as a service (SaaS)

By adopting Cloud technology businesses can reduce costs of acquiring & maintaining the underlying IT hardware infrastructure.  The “pay-as-you-go” model used to charge for these resources by most vendors makes them a more cost-effective solution than owning them, as customers only pay for what they consume.  The ability to scale the size of the solution up or down accommodates for the peaks & troughs in usage, saves the customer money & also gives great flexibility.  Other benefits of cloud computing include guaranteed uptime & security standards that comply with global standards for data protection & privacy
