What Are We GoingTo Talk About

NO silver bulletsNO group-think NO fixation on the sexy-shiny

LAMP is dead

LONG LIVE LAMP

Why do people hate LAMP so much?

PHP Application Stacks

LinuxApacheMySQL

PHP

PHP Application Stacks

Linux | OS-X | WindowsApache | Nginx | Lighttpd | IIS

MySQL | Postgres | SQL Server | Mongo | Couchdb

PHP + Javascript

The cool kids might say otherwise...

LAMP is good enough for YOU

Worry about PSS(Precious Snowflake Syndrome)

TOY

vs.

BUSINESS VALUE

What is a basic PHP application?

Something that accepts a requestSomething that persists data

Some that routes your requestSomething that displays the response

Explosion of PHP Frameworkscauses a lack of focus

Built for the webShare-nothing

3rd party integration

SOMETHING THAT ACCEPTSYOUR WEB REQUESTS

Apache?Lighttpd?Nginx?

IIS?

IT DOES NOT MATTER

Every choice can handlemodern needs

URL re-writingAbility to pass through dynamic requests

Compressing data before serving

STFU And Tell Us!

Apache – well-understood, easy to get helpNginx + Lighttpd require PHP configuration

New tools required for monitoring FCGI

Web-server modules are the keyApache + Nginx works too!

SOME PERSISTENCEOF DATA

NoSQL or RDBMS?Clustered or not-clustered?

DEPENDS ON THE DATA

Domain model?

Heavy reads?

Heavy writes?

STEP 1: FIGURE OUT RELATIONSHIPS

STEP 2: FIGURE OUT USAGE PATTERNS

STEP 3: PROFIT?

DATA MODEL

Key-value?Document?Relational?

RDBMS are high-performing and reliableMake great key-value stores (ala Reddit)

MySQL will never page you at 3 AM due to obscure replication bug

UNSEXY GETS THE JOB DONE

You Are Not Google

“The sooner your company admits this, the sooner you can get down to some real work. Developing the app for Google-sized scale is a waste of your time, plus, there is no way you will get it right. Absolutely none. It's not that you're not smart enough, it's that you do not have the experience to know what problems you will see at scale.”

STFU and Tell Us!

SOMETHING THATROUTES YOUR REQUEST

ROUTING ISNOT SEXY

SOMETHING THATROUTES YOUR REQUEST

Frameworks the quickest wayWeb server rewrite rules for the hardcore

Front controller or page controller

STFU and Tell Us!

System should react to HTTP verbsSystem should allow reuse of URLs

SOMETHING THATDISPLAYS THE RESPONSE

TEMPLATING SYSTEMSARE NOT SEXY

SOMETHING THATDISPLAYS THE RESPONSE

Frameworks the quickest wayDesigners can learn PHP too!

Careful about use of custom tagsPHP is a TEMPLATING LANGUAGE

STFU And Tell Us!

Picking a templating “language” is simply yak shaving

STFU And Tell Us!

What stack you use actually matters very little

Essential Add-ons

Alternate PHP Cache(APC)

Opcode caching for performanceUser-space caching

Essential Add-ons

Memcache

In-memory key-value storageMembase (Memcache + persistence)

Redis (Memcache compatible)

TO THE CLOUD!

What Orchestra Offers

“The idea is that we aren't the dated LAMP stack but rather a more modern nginx, load-balanced, caching, php-fpm, mongo, etc.”

“A platform built for today and tomorrows needs instead of a traditional platform made to handle the problems we had 10-15 years

ago.”

Now Architecture Matters

Performance differentCount on components disappearing

Application architecture matters!
