NetScaler and Fastly are products competing in content delivery and load balancing. NetScaler holds the upper hand in feature richness and support, while Fastly leads in speed and modern technology offerings.
Features: NetScaler provides robust load balancing, application acceleration, and advanced threat protection. Fastly offers real-time logging, edge-compute capabilities, and seamless caching solutions.
Room for Improvement: NetScaler could improve by enhancing its speed and agility. The user interface may also benefit from modernization. Fastly could improve by expanding support and feature offerings, and integrating more comprehensive application control features.
Ease of Deployment and Customer Service: NetScaler uses a traditional deployment model noted for dependability and extensive customer service. Fastly features rapid deployment capabilities and responsive support, ideal for swift implementation and agile operations.
Pricing and ROI: NetScaler typically has higher initial setup costs, justified by its extensive feature set and potential long-term ROI. Fastly is competitively priced, offering significant ROI through efficient scaling and adaptability, favorable for businesses seeking rapid return and scalability.
Reducing infrastructure costs by 40 to 60% because Edge Caching minimizes backend traffic, resulting in lower computing costs.
I have seen a return on investment, particularly in time savings, especially regarding the changes.
demonstrating the team's technical expertise in CDN and Edge architecture
We have SLAs defined because we opted for enterprise support pricing.
I would describe Fastly's customer support as fast and efficient when I have had to use it.
Seamlessly handling massive traffic without requiring backend changes due to its globally distributed Edge network and stateless API-driven design.
Highly reliable for enterprise-scale applications with high uptime guarantees.
I chose 8 out of 10 because it has excellent performance and low latency delivery, making it suitable for larger applications, with strong Edge Caching and instant purging capabilities.
Fastly could improve by improving the documentation and having some code examples.
Fastly should provide features similar to Cloudflare regarding a block list.
It operates on a pay-as-you-go structure, but costs scale with traffic, requiring monitoring to avoid unexpected spikes based on data transfers and the number of requests handled.
In terms of price, I find it good.
We observed a 30 to 50% reduction in response time and a significant reduction in backend load of 40 to 60%, improving visibility through a real-time dashboard for monitoring traffic, errors, and performance.
We have improvements in traceability by having the changes integrated into the Git repositories and having the possibility of doing a rollback in the event of any problem in a very simple way.
In this project, it is working as a reverse proxy for CDN and WAF, web application firewall, additionally image optimization.
