This document discusses hybrid cloud and provides a case study of Algolia's hybrid cloud strategy. The key points are: 1) Hybrid cloud combines private, public, and community cloud infrastructures to provide flexibility, availability, and cost control. 2) Algolia uses a hybrid cloud approach across 17 regions and 80 data centers to provide reliable, low-latency search globally. 3) Algolia uses tools like Terraform, Kubernetes, and automation to manage their complex hybrid cloud infrastructure in a consistent way.

How to build hyper scalable
hybrid clouds

2. Why you should trust me
with Hybrid Cloud
• Closing infrastructure deals
for over 15 years
• 8 years at Leaseweb,
a true Hybrid Cloud provider
• Helping companies move to hybrid
cloud and understand why
hybrid cloud is vital to their business

3. Agenda
• What is Hybrid Cloud
• Advantages of using Hybrid Cloud
• Why Hybrid Cloud is important for
SaaS – Algolia Case Study

4. What is Hybrid Cloud
(Hybrid) cloud infrastructure is a composition of two or more distinct cloud
infrastructures (private, community, or public) that remain unique entities,
but are bound together by standardized or proprietary technology that
enables data and application portability

5. What is Hybrid Cloud
In the past most of us had just one
environment ”cloud". This became
more. Hybrid Cloud also connects
these different clouds

6. Advantages Hybrid Cloud
• Less dependency on just one provider
(control cost)
• Scaling flexibility & availability improvement
• Performance increase (allows you to choose
the lowest latency towards that end user)
• Allows you to keep private & public cloud
separate

7. Algolia Hybrid Cloud
Strategy
In 2014 Algolia was looking for providers with low
latency and extreme high CPU performance,
wanting a hybrid cloud set up immediately
Leaseweb had the perfect solution to match their
needs & now it's one of their main providers for
their large hybrid cloud environment
Adam Surak, Director of Infrastructure & Security at
Algolia, will now deep dive into the why and how
they achieved Hybrid Cloud performance
