with
Amazon
Web
Services

2. Amazon
Web
Services
• a
suite
of
cloud
compu0ng
services
offered
by
Amazon
• highly
reliable,

low-­‐cost
infrastructure
pla>orm
in
the
cloud
• has
more
than
70
services
that
span
a
wide
range
including
compute,
storage,
networking,
database,
analy0cs,
applica0on
services,
deployment,
management,
mobile,
developer
tools
and
tools
for
the
Internet
of
things
• most
central
and
best-­‐known
of
these
services
arguably
include

you
actually
need;
no
minimum
spend
needed
• Agility
and
Instant
Elas2city
– instead
of
wai0ng
weeks
or
months
for
hardware,
you
can
instantly
deploy
new
applica0ons,
instantly
scale
up
as
your
workload
grows,
and
instantly
scale
down
based
on
demand
– one
virtual
server
or
thousands,
whether
you
need
them
for
a
few
hours
or
24/7,
you
s0ll
only
pay
for
what
you
use

6. Auto
Scaling
• helps
you
ensure
that
you
have
the
correct
number
of
EC2
instances
available
to
handle
the
load
for
your
applica0on
• create
collec0ons
of
EC2
instances,
called
Auto
Scaling
groups
• specify
the
minimum
number
of
instances
,
maximum,
and
the
desired
capacity
– minimum
-­‐>
Auto
Scaling
ensures
that
your
group
never
goes
below
this
size
– maximum

7. BeneGits
• Be?er
fault
tolerance
– can
detect
when
an
instance
is
unhealthy,
terminate
it,
and
launch
an
instance
to
replace
it
• Be?er
availability
– can
help
you
ensure
that
your
applica0on
always
has
the
right
amount
of
capacity
to
handle
the
current
traffic
demands
• Be?er
cost
management
– can
dynamically
increase
and
decrease
capacity
as
needed.
Because
you
pay
for
the
EC2
instances
you
use,
you
save
money
by
launching
instances
when
they
are
actually
needed
and
termina0ng
them
when
they
aren't
needed

8. Services
Needed
•
EC2
– provides
scalable
compu0ng
capacity
in
the
Amazon
Web
Services
(AWS)
cloud
– you
can
launch
virtual
servers
as
you
need,
configure
security
and
networking,
and
manage
storage
ELB
– automa0cally
distributes
incoming
applica0on
traffic
across
mul0ple
Amazon
EC2
instances
in
the
cloud
Launch
ConfiguraBon
– template
for
its
EC2
instances
– in
here
you
can
specify
informa0on
such
as
the
AMI
ID,
instance
type,
key
pair,
security
groups

9. Services
Needed
Autoscale
Group
– instances
are
organized
into
groups
so
that
they
can
be
treated
as
a
logical
unit
for
the
purposes
of
scaling
and
management
Security
Groups
– acts
as
a
virtual
firewall
that
controls
the
traffic
for
one
or
more
instances
• S3
– storage
for
the
Internet
• CloudWatch
– monitoring
service
for
resources,
allows
you
to
set
alarms
and
triggers
that
can
be
used
by
other
AWS
services
