AWS Cloud Infrastructure
AWS cloud computing services with automatic scalability and cost optimization
Your application grows, your user base increases, and suddenly you're faced with two problems: a cloud architecture that can't keep up and an AWS bill you don't understand. It doesn't have to be this way. At Mecexis, we've spent over a decade building AWS Cloud infrastructure , and we've learned something fundamental: the cloud is a tool, not an end in itself. We use AWS when it delivers real value, we apply AWS cost optimization so you only pay for what you need, and we guide you so you never again depend on a "cloud guru" that nobody understands.
Why AWS?
The cloud architecture used by Netflix, Airbnb and the Endesa League (yes, we also built it)
Amazon Web Services needs no introduction: it's the world's most widely used cloud computing platform for a reason. It offers 99.99% high availability , a global presence, and a catalog of over 200 services that cover virtually every conceivable technical need.
But here's the problem: most companies misuse AWS. They hire consultants who sell them oversized cloud architectures , pay for services they don't need, and end up with five-figure bills without knowing exactly why.
At Mecexis, we do the opposite. We're not your typical AWS consultancy: we're developers with years of experience deploying real-world applications in production. We know which cloud computing services you need, which ones you can avoid, and how to configure everything with automatic scalability without breaking the bank. We've done it for the ACB with thousands of users, and we do it every day for companies that simply want their applications to work.

Main Advantages of AWS
AWS can be your best friend or your worst nightmare. The difference lies in how you design your cloud architecture . These are the real advantages when you work with a team that knows what it's doing.
-
Real, Not Theoretical Scalability
When the Liga Endesa app experiences a traffic spike during a Real Madrid game, the infrastructure automatically scales in seconds. No manual intervention, no downtime, no surprises. This isn't magic: it's well-configured AWS Cloud infrastructure . Auto Scaling Groups with EC2 , Load Balancers, and a cloud architecture designed from day one to grow with you. And when the game ends, the infrastructure scales down and you stop paying.
-
Predictable and Optimized Costs
The dreaded moment for many businesses is opening their AWS bill at the end of the month. We implement AWS cost optimization with budget alerts, reserved instances where it makes sense, lifecycle policies in S3 , and regular reviews. The result: you know exactly what you're going to pay, and that number is the lowest possible for your needs.
-
Enterprise-Level Security
AWS provides cloud security certifications your company could never achieve on its own: ISO 27001, SOC 2, GDPR, PCI DSS. But certifications are useless if the configuration is incorrect. We implement IAM with least privilege, VPCs with private subnets, encryption in transit and at rest, and regular audits. Your application is compliant because it's configured to be compliant.
-
Global Availability
Do you have users in Europe and Latin America? CloudFront distributes your static content from the edge closest to each user. Need to comply with data residency regulations? We deploy in the region you need. Do you want high availability with geographic redundancy? We configure replicas in multiple Availability Zones. AWS has a presence in 32 regions worldwide, and we know how to leverage it.
-
Unified Development and Production
No more "it works on my machine." With our AWS Cloud infrastructure , development, staging, and production environments are identical. Infrastructure as code with Terraform, automated deployments, and instant rollbacks if something goes wrong. This means fewer bugs in production, more frequent deployments, and development teams that aren't afraid to push changes.
-
One Partner, Not Two Suppliers
Most companies hire one agency to develop their application and another for cloud computing services . The result: when something goes wrong, they blame each other. With Mecexis, you have development and infrastructure under one roof. We build the application and deploy it. If there's a performance issue, we know whether it's code or configuration, and we fix it. No excuses, no ticket-based back-and-forth.
Ideal use cases
AWS is the solution when you need to go further
- Applications with unpredictable traffic spikes that require automatic scalability
- Platforms that process real-time data with Lambda (streaming, IoT, analytics)
- Startups that need rapid cloud migration without hiring an infrastructure team
- E-commerce with high availability on key dates (Black Friday, sales)
- Mobile applications with authentication, notifications, and S3 storage
- Companies that need to comply with cloud security or data residency regulations
AWS services that we master at Mecexis
AWS has over 200 cloud computing services , but the reality is that 90% of applications only need 10. These are the ones we master to build your cloud architecture .
Why choose us as your cloud computing partner?
There are many AWS consulting firms. Most will sell you complex cloud architectures because they charge based on complexity. We charge based on results.
More than a decade building AWS Cloud infrastructure

Developers First, DevOps Later
-
We're not an infrastructure consultancy that outsources development. We're developers who have learned about infrastructure because it's impossible to build good applications without understanding where they'll run. This perspective changes everything: we don't design pretty architectures in a diagram, we design architectures that work for the actual code we're going to deploy.

Pragmatism over Dogma
-
AWS for everything? Not necessarily. If your application doesn't need automatic scalability to millions of users, a VPS at Hetzner might be enough and save you thousands of euros a year. We'll tell you. And if you really need cloud migration to AWS, we'll use exactly the services you need, nothing more. We don't sell technology, we sell solutions.

Infrastructure as Code, Always
-
Everything we deploy in your cloud architecture is documented in Terraform or a similar framework. If you decide to switch providers or manage the infrastructure internally tomorrow, you have all the code. No vendor lock-in with us, no secrets, no artificial dependencies. The AWS Cloud infrastructure is yours; we just build it.

Proven Results at Scale
-
The ACB app we developed serves thousands of basketball fans in Spain, with massive traffic spikes during important games. It never crashes. That's not luck: it's a well-designed cloud architecture , properly configured automatic scalability with EC2 and Lambda , and a team that knows what it's doing. When we say we know how to scale, we have the metrics to prove it.
