ClickMeter

100k+ customers

Getting events for customers from 10 to 3000 req/sec


ClickMeter

We receive data anytime someone: Clicks our links

Views our pixels

Calls our postbacks

Our customers use us: Inside a famous app the day of the big release ✔

Advertising on an extremely big video portal ✔

A tiny travel blog ✔

A physical device for advertising ✔


Getting the data

We need to:

Try not lose the events we receive (duh)

Show to customers data for better insight on their campaigns

Scale up/down according to the incoming fluxes

Improve the product by using the data we get

Do it as fast as possible (wasn’t this ready a week ago?)

Do it as cheap as possible


The challenge

Find the size of the problem you’re trying to solve How much data do you expect? Rate?

What do you have to do with it?

Do I have to do something with ALL of it?

How fast do I have to do it?

Answers to these questions are a starting point.


Size

Once we know how big and bad the beast is, we

need to design the ranch that will keep it in check.

Iterative process and prone to a lot of failures, but

the world is out there to help us.

Think, write and draw a lot.


Design

… drawn too much ...


Design

Most of us will never have the joy (and the horror) of

creating a new stack novel in theory and practice.

Still we need to understand the theory behind every

brick.

Read the info, read the opinions, try little proof of

concepts of the moving parts, it helps a lot!


Which bricks should I use

A very important brick.

Elasticity of computation power, many *aaS, managed solutions are

really a great help in terms of saved manpower and fast iterations.

It comes at a great cost to consider:

• $$$ (ymmv)

• Possible lock-ins


The cloud is a brick too

… well it’s never definitive ...


Design with bricks

Obviously we haven’t followed those guidelines.

One becomes savvy after crashing and burning

many times.

But still thanks to those errors we got there and

built, at every iteration, a better infrastructure.


How we did it

ClickMeter was already live and growing

It needed an overhaul in its infrastructure/backend.

The growth fueled the need to be ready for more power to handle more data.

Obviously this had to be a tablecloth trick migration


How we did it

Already on the cloud (AWS), we thought of having an hybrid approach but it

didn’t make sense.

Review of old components already in production to see what to kill, keep or

update.

Kept good stuff and designed some new layers to make them work flawlessly in

the new infrastructure.


How we did it

Pretty important, they need to:

• Stay up

• Scale up/down depending on the income traffic

• Never lose anything

• Be as fast as possible in processing

They’re a custom web app application that undergoes a lot of testing.

We used stuff like Beanstalk, Scaling groups, Load Balancers and Health routing

offered by our cloud provider to manage the webapp scaling/availability

Pipeline

Most of this part uses our cloud provider

technology.

This simplify maintenance and provisioning,

keeping the focus on the value of our product.

Some moving parts are custom made by us to

interact with the cloud technology (might be

proprietary or just repackaged known one).

• Events • Preprocessing• Postprocessing

• DynamoDB


Tracking engineand friends

Combination of real-time and batch technologies.

One of the scaling parts that actually provides value to the customers.

Computes analysis on events data from a simple count to some predictions.

Pipeline

We employ different storage based on speed of delivery and data type.

All the data is accessible via a REST API.

This permits to develop a frontend layer with pretty much ease and allows

customers to take control of the data and use them in way we might haven’t

thought.


Storage and data delivery

Managed services on the cloud help us a lot!

Most of the team can focus on improvements

and shipping (users are happy, so is the CEO).

Some of us (me) still have to be the

CloudOp/DevOp.

p.s.: prepare always a plan b for when you’ll

break things!


Operations

Cloud is typically more expensive of your own metal.

This extra money you’ve to spend is anyway well spent:

• Flexibility

• Easier provisioning

• Easier management

• Easier operations

There are different types of clouds choose wisely.


Cloud co$t$

Creating and managing a “big data” ready infrastructure is no easy task,

but it can be done step by step also by startups.

The cloud is a cool starting ground providing you with many of the toys

you need, so you can focus on what part of “big data” gives you value!

Use the wisdom shared by the big/medium players that already have

been there(and built most of the stuff you’re using).
