Platform Operations

Apigee Edge is comprised of several stateless components that use infrastructure services to persist data
•  Gateway: Routing and processing API calls
•  Apigee UIs: Enterprise UI, Developer Portal
•  Infrastructure Services: Persistence and queuing of run time data
•  Management Server: Provider of REST APIs for all conﬁguration tasks

Note: Monetization is part of Developer Services and leverages Gateway, Analytics Services and Management Server

•  Router handles all incoming API traffic and dispatches it. The
Router terminates the HTTP request, handles the SSL traffic,
and uses the virtual host name, port, and URI to steer
requests to the appropriate node.
•  Message Processor handles API traffic for a specific
organization and environment and which executes all
policies.
•  Apache Cassandra stores application configurations,
distributed quota counters, API keys, and OAuth tokens for
applications running on the gateway.
•  Apache ZooKeeper contains configuration data about all the
services of the zone and which notifies the different servers
of configuration changes.
•  OpenLDAP contains organization user and roles.
•  Management Server offers an API that is used by the Central
Services server to communicate with the servers in each on-
premises installation.
•  QPID Server manages queuing system for analytics data.
•  Postgres Server manages analytics database.

CAP
Theorem
In theoretical computer science, the CAP theorem, also known as Brewer's theorem, states that it is impossible for a
distributed computer system to simultaneously provide all three of the following guarantees:
•  Consistency - all nodes see the same data at the same time.
•  Availability - a guarantee that every request receives a response about whether it succeeded or failed.
•  Partition tolerance - the system continues to operate despite arbitrary message loss or failure of part of the system.

“Apache Cassandra is an open source distributed database management system. It is an Apache Software
Foundation top-level project designed to handle very large amounts of data spread out across many
commodity servers while providing a highly available service with no single point of failure.” -- Wikipedia
http://cassandra.apache.org/
Cassandra characteristics:
•  All nodes are equal. Not master/slave or primary/secondary.
•  An application can read/write data from any node.
•  Data replication. Apigee Edge uses replication factor 3.
•  Consistency managed by application. Apigee Edge uses one
and local quorum.

Cassandra is used by Apigee for a variety of purposes, including:
•  Storage of developer, application and API Product data
•  Storage of access and refresh tokens
•  Storage of key-value map data
•  Audit logs
•  Custom analytics report models

– Wikipedia

Zookeeper is used by Apigee as a distributed configuration registry, tracking component location, configuration
and status data. With some exceptions, it is NOT required to process API requests.
•  Leader: The node that controls coordination of writes
across distributed Zookeeper nodes
•  Voters: Nodes that can vote on change proposal
made by the Leader
•  Observers: Do not vote on change proposals and
must forward all writes to the Leader

•  Given the responsibility and capabilities offered by
each component, scalability requirements and how
they are implemented may vary.
•  In most scenarios, scaling to accommodate higher
number of TPS or API calls may impact only
components serving live API trafﬁc.
•  Analytics and management components may grow
in number mostly driven by demanding high
availability requirements for those capabilities
provided by analytics and management
components.

Multitenancy
“Multitenancy is a reference to the mode of operation of software where multiple independent instances of
one or multiple applications operate in a shared environment. The instances (tenants) are logically isolated,
but physically integrated. The degree of logical isolation must be complete, but the degree of physical
integration will vary. The more physical integration, the harder it is to preserve the logical isolation. The
tenants (application instances) can be representations of organizations that obtained access to the
multitenant application (this is the scenario of an ISV offering services of an application to multiple
customer organizations). The tenants may also be multiple applications competing for shared underlying
resources (this is the scenario of a private or public cloud where multiple applications are offered in a
common cloud environment).” - Gartner
Multitenancy = Software capabilities to support shared infrastructure "
while providing tenants with data and processing partitioning.

Host

Environment

Regional Services are shared by many pods across a single geographical region and maintain
state and provide an API that works across the pods in a region
Pods are a collection of servers that share logical functions such as a Gateway Pod or an
Analytics Pod.
Orgs provide logical grouping to secure access to API management services. Orgs are associated
with pods for servers – they can either share hardware or be isolated
Environments are virtual routes that allow API bundles to be deployed and tested within and Org.
Environments can be associated with pods for servers independently of the Org.
Virtual Hosts are similar to Apache Virtual hosts and route trafﬁc to environments based on ports
and domain names.

•  Analytics data is partitioned per Environment.
•  Analytics data size generated by MPs per transaction is about 1kb.
•  PostgreSQL contains Raw Data Tables and Aggregated Data Tables. Raw Data Tables grow as
analytics data is collected. Appropriate data retention policy and purge processes are required.
•  Custom reports allow customers to define user-defined queries which run against raw data.

•  Edge architecture does not impose
network zone requirements. Network
zoning will be driven by customer
operation and security requirements.
•  Firewalls and security appliances
between zones should
accommodate the connectivity "
and trafﬁc characteristics of Apigee
components without adding "
latency overhead.
•  Keep API trafﬁc as direct as possible.
Keep MP dependencies close.
•  Pay attention to cross-zone

Private Cloud – Software Install
Apigee Private Cloud (apigee-edge-4.15.07.00.zip) has everything required to install and conﬁgure Apigee Edge
and BaaS components except for the Developer Portal. The Developer Portal is distributed using a different
package (DeveloperServices-4.15.07.00.tar).
Apigee Edge installation steps:
1.  Acquire a license key and copy it to all nodes.
2.  Download the Apigee Private Cloud from ftp.apigee.com and copy it to all nodes.
3.  Installation downloads and installs required system software via Yum. It requires Internet connection or local
repository.
4.  Unzip apigee-edge-4.<YY>.<MM>.<V>.zip
5.  Run the primary installation script:

/<unzip-‐location>/apigee-‐edge-‐4.<YY>.<MM>.<V>/apigee-‐install.sh
-‐j
/usr/java/default

-‐r
<inst-‐root>
-‐d
<data-‐root>


Private Cloud – Software Setup
1.  Once Apigee binaries are installed, run:
/<inst-‐root>/apigee4/share/installer/apigee-‐setup.sh

2.  Setup script requires a proﬁle type and information about the system, provided interactively or via response
ﬁle (silent install).
3.  Create an organization, environment(s) and organization administrator, run:
/<inst-‐root>/apigee4/bin/setup-‐org.sh


Private Cloud – Silent Install
•  Silent install provides a way for specifying, in advance, all necessary values used by apigee-setup.sh
•  Silent install provides a way for specifying, in
advance, all necessary values used by apigee-
setup.sh
/<inst-‐root>/apigee4/share/installer/
apigee-‐setup.sh
-‐p
ds
-‐f
<response-‐
file-‐name>

•  The response files contain a number of variables
definitions to be used by apigee-setup.sh. A
response file per DC/Region will be needed since
some values are unique per DC/Region.
Single machine setups:
•  aio = All In One (Gateway and Analytics Standalone)
Cluster node setup for ZooKeeper and Cassandra (min 3 nodes):
•  ds = Datastore Cluster Node

LDAP setup for OpenLDAP:
•  ld = LDAP Node

Separate components setup:
•  ld = LDAP Node
•  ms = Gateway Management Server
•  r = Gateway Router
•  mp = Gateway Message Processor
•  rmp = Gateway Router and Message Processor
•  qs = Analytics Qpid Server
•  ps = Analytics Postgres Server
•  mo = Monetization Server
Note: The list above doesn’t show all the available options. Refers to Apigee Edge
Install and Configuration Guide, section Basic Host Installation, page 35 for details.
