Capabilities

Typically each field is locked into its own silo

In the world of technology, building a great product requires depth in several fields at once. Most vendors have one. We have them all.

Software Development

Industrial Automation

IT Hardware & Networking

Mobile Development

Four fields converging on one solution — Most vendors own one silo. Simple Tech brings all four together into one solution.

Building a great product requires:

In-depth knowledge and experience in both the specific industry and the numerous fields within the technology sector

Deep understanding of the problems in day-to-day operations

Deep understanding of the requirements from management and operators

Experience in both software and hardware development, particularly industrial systems such as PLC and Modbus as well as UI development

Experience in IT infrastructure and computer networks

Experience in mobile application development to meet the demands of today's hi-tech customers

We have it all.

Evolution of Server Infrastructure

As industry moves towards 4.0, robust and reliable server infrastructure is absolutely critical for minimizing problems and ensuring always-on business operations. There has therefore been a major trend to shift away from traditional server infrastructure towards a hyper-converged environment.

Pre 2011

Traditional

Key Points

Isolated stand-alone physical servers

Application services belong to and exist in each physical server

May have limited redundancy such as dual power supply or RAID storage

Benefits

Simple — only low-level IT personnel is needed

Drawbacks

No way to recover from failure quickly

No way to achieve zero downtime

Time consuming to manage and configure

Hard to backup and restore

No load balancing

Service dependent on hardware — if one server is damaged then all its services are down

2011 – 2016

Converged

Key Points

A hypervisor abstracts server services into virtual machines (VM)

Storage via SAN or NAS, which provides high redundancy so broken hard disks do not bring down the entire system

A fast network, usually 10 Gbps, connects the servers to network storage

Benefits

Software and hardware abstraction — services no longer depend on the physical host and can be moved without shutdown

Automatic load balancing

High availability — when a host breaks down, all its VMs migrate automatically

Easy to manage from a single hypervisor interface

Able to easily backup and restore an entire server

Drawbacks

Extra cost for the hypervisor platform

Extra cost for SAN and NAS

Slow — data read/write goes via the network

Virtualization “sits on top” only

2016 +

Hyper-Converged

Key Points

Computing, networking and storage all combined into one integrated cluster of nodes

Storage via local host SSD and HDD — no need for network storage anymore

The hypervisor platform is integrated into the system

Benefits

All the benefits of converged infrastructure — and much more

Extremely fast — no network hop, storage IOPS 8× faster

Smaller footprint — saves space

Lower power consumption due to fewer pieces of equipment

Linearly scalable — add new servers without powering down

Able to realize always-on operations

Able to backup the entire server via enterprise-grade backup software

Drawbacks

None

Nutanix: the best hyper-converged

Nutanix is a leading provider of hyper-converged infrastructure (HCI) software which virtualizes all the elements in a traditional server infrastructure. As of 2019, the company had 28.9% market share in the HCI space.
