Multi-cloud transit improves the application experience but poses complexity and security issues



Sapio Research surveyed more than 400 IT managers in US-based organizations with more than 1,000 employees. network and security. The results show that while multi-cloud transit can dramatically improve network latency, the move to multi-cloud also introduces significant complexity and security issues.

The report examines the performance of single cloud, multi-cloud, and direct internet connectivity. Multi-cloud is the clear winner in terms of performance: For user-application connectivity, multi-cloud has been shown to reduce network latency on 45% more paths than a single cloud, while improving performance up to 55% per path, versus network – centric connectivity like VPN and SD-WAN.

Businesses agree that a great app experience is the key to business success

While 93% of organizations agree that the application experience is important to the overall success of the business, 64% find that they are unable to deliver the same level of experience to everyone, while 47% state that it is impossible to keep up with the diverse landscape of applications and users.

Growing diversity of applications adds complexity

Different types of applications experience significant variation in performance, even when connecting on the same routes, within the same CSP. Our report found that the variance can be 15-80% from application to application.

Additionally, modern applications have very different architectural and security requirements that impact performance, making monitoring difficult for businesses.

Security and complexity remain critical challenges for multi-cloud transit

Businesses are more concerned than ever with the growing surface of threats caused by multi-cloud transit and the decentralization of users, applications and data around the world. To solve this problem, many corporate security teams have turned to VPNs or inserting security provider SaaS services to enforce user and application security policies.

However, inserting a mid-mile SaaS infrastructure can dramatically slow performance – adding 28 times the latency, compared to a solution that eliminates the mid-mile SaaS infrastructure and brings security closer to end users.

Gaps between routes and CSP make it difficult to select an optimal transit route

The variance between key routes between CSPs can vary widely, adding additional complexity. For example, the report finds that Singapore’s UK latency had a gap of 50MS + between the three CSPs; and the latency from Hong Kong to Australia had a deviation of 20MS.

Additionally, it underscores the dynamic nature of cloud networks; the number of users, data volumes, connectivity options, routes, and other factors can impact overall performance at any given time.

To realize the promise of multi-cloud transit, organizations must simplify their infrastructure

While 94% of organizations currently use tools to measure application experience, the report finds companies lack comprehensive tools to measure user-to-application and application-to-application performance, on key routes, vendors. cloud and types of applications.

“Despite the main challenges, multi-cloud remains a very attractive strategy for companies that need to deliver fast, secure and consistent application experiences across the world,” said Ramesh Prabagaran, CEO of Prosimo.

“Given the complexities involved, successful organizations will develop a balanced approach – one that manages cost, security and performance. As a result, multi-cloud networking alone will not suffice; businesses will need a strategy that combines multi-cloud networking, security, application performance, and observability in an integrated stack.
