Key Takeaway
- Network integration services cover the design, configuration, and management of the connections between your on-premises systems and cloud environment.
- Performance problems after go-live, such as slow applications or unreliable connections, often trace back to network planning that happened too late or not at all.
- Businesses running hybrid setups need the network layer to account for bandwidth, latency, and security across both environments at the same time.
- A network health check before cloud migration identifies gaps in your current setup before they become production problems.
- Choosing a network integration partner with vendor authorisations from the hardware manufacturers already in your environment reduces the risk of misconfiguration.
Introduction
When businesses plan a move to the cloud, attention goes to which applications to migrate, which cloud provider to use, and what the costs look like. Network integration services are where the plan often falls apart.
The network carries data between your on-premises servers and the cloud. If that connection is not designed for the demands of a hybrid setup, applications slow down, transfers become unreliable, and the cloud setup you paid to build does not deliver.
What Are Network Integration Services and What Do They Actually Cover?
Network integration services cover the design, implementation, and ongoing management of the network infrastructure connecting your systems to a cloud environment on AWS.
The work covers several areas:
- Wide area networks (WAN), which connect geographically separate locations to cloud environments
- Local area networks (LAN), the internal network within your office or data centre
- Wireless networks for locations where devices connect without cables
- Enterprise network switches and routers that direct traffic between systems
- Security controls including firewalls and access policies that define what traffic is permitted
Data centre networking, the high-speed connections between servers, storage, and switches inside a data centre, is a specialised part of this work. How that internal network is designed directly affects how well your systems communicate with the cloud once migration is done.
Why Does the Network Break Down When Businesses Move to the Cloud?
When workloads move to the cloud, data travels between your premises and a remote data centre instead of staying on a short local connection. Three factors drive most post-migration network problems.
Bandwidth
Bandwidth is the volume of data your network connection can carry at one time. In a hybrid environment, large data transfers, backup jobs, and application traffic all compete for the same connection. If it is not sized for the actual workload, it becomes a bottleneck.
Latency
Latency is the time it takes for data to travel from one point to another. According to the AWS Well-Architected Hybrid Networking Lens, internet-based connections introduce variable latency because the route data takes can change at any time. For databases, transactional systems, and real-time reporting tools, this causes visible performance problems.
Security Misconfiguration
When traffic crosses between on-premises and cloud environments, firewall rules, access controls, and encryption settings all need updating for a hybrid environment, not just for the on-premises systems they were originally built around.
The network is not something you configure after migration is complete. It determines whether the migration performs as expected from day one.
What Should a Network Health Check Include Before Cloud Migration?
A network health check assesses your current infrastructure against the demands your cloud setup will place on it. The AWS Well-Architected Framework states that organisations should estimate bandwidth and latency requirements before selecting a connection type, because those numbers drive the sizing of the link to the cloud. Skipping this is one of the most common reasons businesses see underperformance after go-live.
A network health check should cover:
Current Bandwidth Capacity
How much data does your network carry now, and how will that change when applications run in the cloud and communicate back to on-premises systems?
Latency Baseline
What response times do your most performance-sensitive applications currently need, and what will they tolerate across a hybrid connection?
Connection Type
A VPN (Virtual Private Network) creates an encrypted tunnel over the public internet. It is faster to set up and lower in cost, but latency varies. AWS Direct Connect is a dedicated private connection that provides consistent, predictable performance, suited to production workloads where reliable response times matter.
Security Policy Review
Firewall rules written for on-premises traffic need to be reviewed before cloud traffic flows through them.
Redundancy
A single connection to the cloud is a single point of failure. The assessment should confirm whether redundant connections are needed.
A network assessment tells you whether your current infrastructure can support the cloud setup you are planning, before you find out the hard way.
VSTECS KU’s professional services team conducts network health checks as part of pre-migration assessments, producing specific findings on bandwidth gaps, latency concerns, and security policy issues before go-live.
How Does Data Centre Networking Support a Hybrid Cloud Setup?
Data centre networking covers the high-speed internal connections between servers, storage, and switches inside a data centre. In a hybrid cloud setup, this internal network connects to the cloud through a VPN or Direct Connect link. How it is designed directly affects how fast and reliably data moves between the data centre and the cloud.
Three things matter most:
Switching Capacity
Data centre switches need to handle both internal server traffic and outbound traffic to the cloud. As cloud workloads grow, the volume crossing that boundary increases. Switches sized only for internal traffic may not cope.
Network Segmentation
Production traffic, backup transfers, and management traffic should each move through separate network zones. Without segmentation, workloads compete for the same capacity and security controls become hard to apply consistently.
Routing Design
Traffic follows paths defined by routing policies. Policies designed for a purely on-premises environment can push traffic down inefficient routes, adding latency and unexpected data transfer costs.
VSTECS KU works with Cisco, Palo Alto Networks, Juniper, and Huawei across its enterprise network engagements. These are the same platforms Malaysian enterprise data centres run on, so integration work fits into existing environments without requiring hardware replacement. The AWS cloud solutions team handles the cloud side, including Amazon VPC configuration and AWS Direct Connect setup, so that both environments are designed to work together from the start.
What Should You Look for in a Network Integration Partner?
Vendor Authorisations
Working with Cisco, Palo Alto Networks, Juniper, and Huawei equipment requires engineers who have been trained and assessed by those manufacturers. This means the people configuring your network have been verified against the standards of the equipment they are working on.
Cloud Platform Knowledge
The on-premises network and the cloud environment have to be designed together. A partner with no experience in AWS VPC design or Direct Connect cannot do this properly.
Pre-Migration Assessment
The partner should assess your environment before starting work and produce specific findings on bandwidth, latency, and security, not a general recommendation to upgrade.
Ongoing Support
Network requirements change as cloud usage grows. A partner with managed services capability can monitor the network and make adjustments before problems reach users.
VSTECS KU holds authorised support status from Hewlett Packard Enterprise, Palo Alto Networks, Juniper Networks, and Huawei. As Malaysia’s first authorised AWS distributor, it gives businesses a single point of contact for both the on-premises network and the AWS cloud infrastructure it connects to.

Frequently Asked Questions
1. What are network integration services?
Network integration services cover the design, configuration, and management of the network infrastructure connecting on-premises systems to cloud environments, including connection type selection, security policy configuration, and ongoing monitoring.
2. Why does the network matter so much during cloud migration?
The network carries all traffic between your on-premises systems and the cloud. If it is not designed for a hybrid environment, applications slow down, and performance problems follow. These almost always trace back to network decisions made during the planning stage.
3. What is the difference between a VPN and AWS Direct Connect?
A VPN creates an encrypted connection over the public internet. It is quicker to set up, but latency varies. AWS Direct Connect is a dedicated private connection that provides consistent, predictable performance. The right choice depends on your workload requirements.
4. What is data centre networking and how does it relate to cloud infrastructure?
Data centre networking covers the high-speed internal connections inside a data centre. This internal network links to the cloud through a VPN or Direct Connect. Poorly designed internal networking creates bottlenecks that no amount of cloud infrastructure investment can fix downstream.
5. What should a network health check before cloud migration cover?
Bandwidth capacity, latency baseline, connection type selection, security policy review for a hybrid environment, and redundancy planning. It should happen before migration begins, not after performance problems appear.
